LateralGM 1.8.6.844

[egofree]

I had similar problems several days ago, but i am was not sure if it was due to ENIGMA or not. This morning i installed the new version of LateralGM, and after several seconds i had again a black screen. As i saw nothing, i could not even use the tasks manager. I had to use the 'off' button of my computer. If you think it's due to the hardware acceleration, please disable it by default !

[Goombert]

Heh, you don't understand, the default by the JVM is actually on if the hardware supports it. The real issue is further bugs down inside LGM like executing GUI/Swing code on the EDT. But I will be turning the default to forcing it off in the next release.

But i am not 100% sure. This week i had several updates for my Nvidia graphic drivers, and this could be the problem also.

Quick update with some small changes. You can update via python install.py or by manually downloading the new jars.

* The MDI area scrollbars are now only shown when needed, so when you maximize a frame they will not be visible, just like normal MDI managers and the one in GM8.1, giving just a little more space on screen.

* Hardware acceleration is now forced off by default again, though I still need you guys to run it with it on and report issues to me because regardless of whether or not we fix them they still exist and only get worse as time goes on, the whole point of what I'm trying to do is fix these bugs and eliminate them for good which I can't do if you guys don't report them.
* Fixed a regression I accidentally left in the source code that caused the MDI frames to have skinny title panes under some look and feels, when testing I was setting the UI property "isPalette" on the frames.
* Fixed class cast exception when changing the window decorations preference caused by having open MDI frames.

From my research it seems that users with Nvidia graphics cards have the most problems with Java2D's hardware acceleration. Regardless, I still need issues reported to me because either way I can try to fix what needs to be fixed, I do not want to sweep issues under the rug, that's how LGM got so buggy in the first place.

What is the purpose of the event selector icon in main window (on the top-right) ? It doesn't seem to be implemented. If i click on an event, i've the following error : http://pastebin.com/4SeQtzBp.

[Goombert]

If you click that button, it should raise the event tab, unless you set the preference to undock it in which case it shows the frame. Also, the latter error log does not help me, I have no way of reproducing that and failed in doing so, everything seems to be working here, I need exact steps.

[egofree]

I can't reproduce the error anymore. But why this event selector is in the main toolbar ? It's only for objects. It should be in the objects window. If you don't have an object open, it can't be used. This doesn't seem logical to me. This icon seems useless to me in this place. It is also displayed when you are in the objects events and you click on the modify button.

Here's another update that took me a while to complete. As always python install.py to update or manually download the jars from Extra Packages.

* Icon reading exception fixed by sorlok for some ico files that have empty/fake masks.

* Implemented undo and redo to the action list editors you can undo multiple actions such as move, cut, copy, paste, delete, and clear. The only thing that does not yet get undone is changes to the actions values, not even recognized yet as an undo operation.

* Fixed exceptions for some file open dialogs when you enter a filename for a file that does not exist. This needs further cleaned up.
https://github.com/IsmAvatar/LateralGM/commit/e5785eff85ced88d09e6ce4389c1228e5b849dee
* Added APNG loading to the sprite and background editor, the file extension will need to be ".apng" for LGM to load all the subimages from it, or it will think it's a regular PNG. It can be used to mix GIF's and APNG's in the sprite editor. This required moving the APNG reader/writer from the plugin to LGM.

In the following image you can see I mixed a sonic GIF with another APNG image, and also loaded another APNG image separately.


I encourage everyone to experiment with the action list undo implementation and ensure that everything works as you would expect and that undoing/redoing does not throw any exceptions, try as hard as you can to break it. And remember, try to also make an example with steps that I can easily reproduce for me to fix it. This is a very tricky feature and requires careful analysis.

It has been in there since LGM was first started egofree, it's kind of unique to the application, occasionally I click on the button as well to get the panel. If you think it should be removed you should discuss it with everyone else, I personally don't have an opinion on it either way because if you don't use it, it's not in your way so it shouldn't bother you.

What is the action list editors ? 

[Goombert]

The drag and drop component that is on the timeline frame and object frame? Drag and drop actions, hence Action List editor.

Ok, but how can the undo and redo can be accomplished ? I don't see any buttons for this.

[Goombert]

The clipboard, CTRL+Z/CTRL+Y and also the context menu, Right Click->Undo/Redo just like GM: Studio

[egofree]

Ok, i understand now. There is a problem with the focus. Within the objects window, if the actions list panel doesn't have the focus, the keyboards shortcuts don't work. I give an example : if you add several  new actions, and try CTRL-Z, it doesn't work if an action has not been selected before in the actions list panel.

Edit:
To be sure, just open a new objects window, and add directly new actions. It will not work. You have to select an action in the actions list panel. Would it be possible to link the shortcuts to the objects window and not the actions panel ?

[egofree]

By the way, it doesn't seem good to have functions like the undo, which are not always present in every part of the program, if there is no indication for the user that it's available. So my advice would to add at buttons to show to the user that this function is available. I see two possibilities : first we add a specific tools bar to the objects window, or we add dynamically these buttons in the main toolbar (next to the events selector button).

Edit:
It's the same with the 'expand all', 'collapse all' functions within the search results. It seems to me dangerous to have functions only available in a context menu. I am sure a lot of people will never see that these functions are available.

I sent an email to IsmAvatar about this.
