Hello!
I create tutorial about "creating first game in enigma", it is in Polish, but I want to translate in English. My Language isn't very well, so If somebody can upgrade them.
Hello !
Many people like to play computer games. Some prefer platformers , some bashing , FPS , MMO ...
But few forms game - it seems to be difficult and time consuming ;)
I will try to show you that creating games , it's quite simple ( though sometimes time consuming ) game , in which " takes on " the God : P How else to create something called according to his own ideas ? Of course, we do not have power , but something we create .
First, we should be provided with something in the game where you can create , generally know the two programs, " a fashion " (ie tested ) , and a third did not understand . But then I'll go : D
- Game Editor
Game Editor is a simple clicker , which first of all you need to know English. While most things can be use , then you need to know what to use. The project itself is licensed under the GPL and can convert a number of platforms (mostly old phones and basic three operating systems ( although you can try to compile on BSD or other systems )
- Enigma - dev ( I'm going to use it )
Enigma is intermediate program (if you can call it that) - In general, you can create games by amateurs and by advanced users (of course, the more we can, the more we create miracles ) , based on the EDL ( Enigma Development Language). In general, you can call the program a clone of Game Maker ( Boys generally try to achieve compatibility )
- SandBox Game Maker ( entering into deep water , resort )
Although I tried to learn it - I lost . SBGM used to create RPG , FPS and platforming in 3D ( on the Cube 2 engine ), generally everything looks brilliant and as he was being mastered , it has to beat a lot of games open source ( and of high quality , something I have to play the game: P)
1 ) Planning
The first thing we should do is plan a little bit about the game. It should be given to a few things out (which I write ) . The basic principle - not a figment of 3D games with the campaign at 5000h and wonders on a stick . In fact, if enigma is able to create such wonders , you do such a game would take probably a couple of years . Since you're a beginning filmmakers , we should create a game with minimal complexity , mainly because these things quickly creates (ie quickly see the effects ) and you can quickly end.
The second thing is the graphics, if you do not play text , we should think about it. The problem here is that either create it in paint (or something else ) , or someone will take care of . The problem is that if we can not draw in paint is better not to take . A person who is for us to make - usually smack it ( sad truth ) and the project itself is dying. Top here before the show tileset'y ( graphics) and in the selected game. We should look at : http://opengameart.org them.
Music and sound - this generally is a big problem . You can of course use something or take away from other projects ( why not? ), But do not always fit. It should also be noted that, as you take something from another project , on what license the thing is .
It is from Google Translator with little changes.

Hello!
Many people like to play computer games. Some prefer platformers, some racing, FPS, MMO, etc.
But few people ever learn to program, usually because it seems to be difficult and time consuming :)
I will try to show you that creating games is quite simple and can be a lot of fun. In which you basically take the role of God in creating your own digitally interactive worlds.
First, we need to pick out a few tools to use and a game engine that will run our game. There are a lot of popular rapid application development tools for games including ENIGMA, Unity3D, and Blitz Basic.
- Game Editor
Game Editor is a simple point and click tool, which you need to know English to use. While most things can be easy to use, then you need to know which to choose. The project itself is licensed under GNU GPL and can convert a number of platforms (mostly old phones and basic free operating systems (although you can try to compile on BSD or other systems)
- Enigma - dev ( I'm going to use it )
Enigma is an intermediate program (if you can call it that) - In general, amateurs can create games as well as advanced users (of course, the more we can, the more we create miracles) , based on EDL (Enigma Development Language). In general, you can call the program a clone of Game Maker (the developers generally try to achieve compatibility)
- SandBox Game Maker (entering into deep water , resort)
Although I tried to learn it - I failed. SBGM used to create RPG, FPS and platforming games in 3D (on the Cube 2 engine), generally everything looks brilliant and as it was being mastered, it has to beat a lot of open source games (and of high quality , something I have to play the game :P)
1 ) Planning
The first thing we should do is plan a little bit about the game. To start we will create a basic game since you are simply starting out and do not want a lot of complexity yet.
The second thing is graphics, as games require a lot of high quality art and animation. The problem here is that usually developers and coders are not very good artists and rely on others talents. Another problem is finding a suitable paint program, there are a lot of popular free ones such as Paint.net, which is preferred by ENIGMA's lead developer Robert, as well as Gimp which is available cross-platform. You can also find a lot of free graphics content on the web, You should take a look at : http://www.opengameart.org.
Audio and Video - these two are usually a big problem for indie developers without money to hire musicians and artists, you can of course use free and open source media found on many popular websites, just so long as you be careful about copyright infringement. However usually games that do have their own custom content can be a lot more appealing.
Give me a minute, still translating...
Edit: There I think that is pretty good.

2) Create appropriate
It is worth noting that "my game" is just an example, so do not firing on full-sized platformer (and most of its nucleus)
http://opengameart.org/content/outside-tileset
I chose this tileset is simple and will quickly take advantage of it.
First, we should start with the main character, cut it in Paint (I use the Pinta, but KolourPaint is also good), create a new Sprite, paste it and call the graphics properly (I recommend the use of the names spr_name, because the objects (and other things) can not be called just a spr_hero (for example) can easily be mentally associate with obj_hero (etc.).
It should create an object (obj_hero) and assign an image (spr_hero), create a new room and set the figure there.
2) Move the hero
Each character in the game should not move (unless you play dead man, or no character). We will move to the right, left, up (down to decline at most)
-
I am going to move this since this does not fit the criteria of W.I.P. give me a minute to translate it.
2) Picking Names
It is worth noting that "my game" is just an example, or a prototype, if you will, so it is not meant to be a full blown platformer.
http://opengameart.org/content/outside-tileset
I chose this tileset because it is simple and we can quickly take advantage of it.
1) Character Control
First, we should start with the main character, draw it in Paint (I use the Pinta, but KolourPaint is also good), create a new Sprite, paste it and name the resource properly. Since resources are actually variables they should and must follow the same naming conventions, i.e. do not add weird characters or spaces, underscores are fine, and do not make the first character a number. The standard is usually prefixing sprites as spr_* and objects as obj_*, etc. It is also more sensible to name the objects and other resources what they represent such as a player object would be called obj_player, etc.
You should create an object (obj_hero) and assign an image (spr_hero), create a new room and place the instance there.
2) Movement
Each character in the game should not move, unless of course you are in a sort of spectator mode. We will move to the right, left, up and add a little bit of gravity.
Edit: Done.

It is worth to know basic math - X and Y (ie, Cartesian ) .
But if the object obj_hero we need to add events (events ), which will be pressing (Keyboard ) → right , left and up ( turn add )
The walk to the right using the code :
x = x +3
This means adding to X the number 3 (where X is the position of the character) and save as X (the new X is X + 3 )
Similarly, we left ( only that subtracting )
To make the jump is not enough to make y = y 3 for a simple reason , the change in position Y to make " climbing the ladder " (or something like that ), where there is no gravity , we will use
if !place_free(x,y+1)
vspeed=-8;
What happens is that if you do not have on one another ( no object ) is a vspeed ( Vertical Speed) is -8 .
By the way, let's add gravity (which we will drew down) , you can use the Event "Step" ( the loop is repeated all the time code ) , and enter the
if place_free(x+0,y+3)
{
gravity=0.25
}
else
{
gravity=0
}
if(vspeed>8)
{
vspeed=8
}
-
Ugh, I need a break fervi ^_^ I'll translate that one later.
-
ok, no problem

So fervi, you are Polish or you just found a Polish tutorial that you want to translate? I didn't really get it.
-
I wrote (in Polish) tutorial how to create a game to promote enigma-dev and show how easy it is. But I think this tutorial should also in enigma-dev (english).

It is helpful if you already know basic highschool geometry and math, for instance the Cartesian coordinate system is used to map objects and graphics on the screen as well as calculate collision detection and make physics calculations. The character object we need to add events to handle the input from the arrow keys and move it accordingly.
We move the object to the right using this code: x = x +3
This sets the x coordinate of the object equal to its current position in addition to 3 pixels. To move left you simply subtract from x.
For jumping we need to add a little more code than what we did for moving left or right. To move the object vertically without accounting for gravity, such as walking up a ladder you would use the following code.
if !place_free(x,y+1)
vspeed=-8;
Basically this code says that if no objects are on top of each other the vertical speed becomes -8 pixels per time step.
Now we can add an extra component, gravity, which will gradually pull the object down. You can add this code to the step event of the object.
if place_free(x+0,y+3) {
gravity=0.25
} else {
gravity=0
}
if (vspeed>8)
{
vspeed=8
}
Done.

It also quickly create a wall, because gravity will consume us down off the screen :)
Temporarily lent itself to the wall of my other project, I added an object and set solid option (which is used in such walls is usually stationary objects)
In obj_hero add event Collision with obj_wall and enter the code:
if (vspeed> 0) {
move_contact_solid (270, vspeed);
}
vspeed = 0;
So that if we will meet our character to the wall, it will not fall
-
We will also need to create an invisible wall for detecting if the object falls of the screen.
Add an object and tick the solid option on it, which is generally for stationary objects.
In obj_hero add a event Collision with obj_wall and enter the code:
if (vspeed> 0) {
move_contact_solid (270, vspeed);
}
vspeed = 0;
This way if the character hits the wall it will not fall.
Done, and I need a break again :P

3 ) Lethal water , or obstacles
The figure ( proposed by the author tileset ) we have a murderous water . Since we like to have a deadly water cut tilesetu water and add to the sprite and create an object obj_water
I chose the darker water ( it does not make any difference )
Now create a conflict of obj_water and set the code
game_restart ();
That is to say that the game (including our position , the collected points [ if they were ] ) will restart , almost as if it just fired
4 ) Land
This is the moment in which obj_wall ( and spr_wall ) dump and replace soil. Specifically, we throw spr_wall , add spr_ground in obj_wall change the sprite to spr_ground , and change the name of the object itself . Phew
5) Background
Author Tilesetu did not give us the background , so either or we 'll get it , or we use a uniform color. I personally like this bright blue like it in the settings of room ( in the Background tab ) changed to a darker color .
6 ) A small earth
Adding even object " small world", which will be the platform . There is nothing like the earth . ( so that the small)
7 ) End of game
Everything has a beginning and an end - we need to add an end . Employ the graphic character ( with an arrow , but whatever ) as our goal.
Here we like , add character , add an object with the graphics of the character in the form of adding a collision with a sign. This time, our code :
game_end ();
turn off the game
8) The amendments visual
To our game look nice , we need to improve it visually - let the water covers the entire territory , etc.
Voila ! The game is over !
Of course we have many mechanisms introduced in the game , such as the prevention of possible escape from the game . But it's in your hands depends on what you do . My role has come to an end , I can die in peace :)

3 ) Drowning and Obstacles
The figure we are using from our tileset includes water which the player can not swim in. First cut the water out of the tileset and add it to the sprite and create an object called obj_water.
I chose the darker water ( it does not make any difference )
Now create a collision of obj_water and add the code
game_restart();
That is to say that the game (including our position, and all other variables) will restart, almost as if it just started.
4 ) Land
This is where we check for obj_wall with spr_wall and replace the soil. Specifically, we throw spr_wall, add spr_ground in obj_wall change the sprite to spr_ground, and change the name of the object itself. Phew
5) Background
The tileset did not give us the background, so either we'll get it, or we use a uniform color. I personally like this bright blue like the default in the settings of the room editor (in the Background tab) changed to a darker color.
6 ) A small earth
Adding even object " small world", which will be the platform. There is nothing like the earth. (so that the small)
7 ) End of game
Everything has a beginning and an end - we need to add an end. Employ the graphic character (with an arrow , but whatever) as our goal.
Here we add a character, add an object with the graphics of the character in the form of adding a collision with a sign. This time, our code is:
game_end ();
// turn off the game
8) The amendments visual
To our game look nice , we need to improve it visually - let the water covers the entire territory , etc.
Voila! The game is ove !
Of course we have many mechanisms introduced in the game, such as the prevention of possible escape from the game. But it's in your hands what you do. My role has come to an end, I can die in peace :)
