[Dev] Bugs that hold you back RELOADED

[Raco]

Hey you BGE enthusiasts!

I may not be the only one with requests for bug-fixes, so I opened this thread for anyone to add some requests of their own. Except let’s only mention those tasks that in your opinion should deserve the highest priority, and let’s keep it at five the most. Also, even if someone else already mentioned a bug that’s in your own top five, be honest and mention it too. This will allow everyone to get a better picture of which bugs are prominent in lowering the potential of the BGE.

As everyone is well-aware that Blender is open source, keep in mind that this thread is no means to force anyone to fix bugs. (So Moguri, since you’re the main developer right now, don’t feel obligated in anyway to address these tasks). However as a side question I would like to ask each one of you how you would feel about writing a letter to the Blender Foundation collectively, to ask for financial support in fixing these bugs.

Don’t forget to link an url to the task description. For example: T18987 alignAxisToVect() Factor Bug

So here’s my top 6 (sorry, couldn’t help it myself , better ignore the last one)

• T40555 Alternating LibLoad and LibFree crashes BGE
  -> Related: T40924 LibNew & LibFree material bug
  -> If LibFree is not working then LibLoad/LibNew cannot be used frequently without causing a memory leak
• T40955 LibNew doesn’t clone Physics Mesh-> Related: T38170 replaceMesh() / LibNew() crashing game engine (closed as duplicate)
  -> Related: T33212 Physics bug in the replaced mesh (not sure)
  -> A lot of potential is in this, would this be fixed
• T39747 Unable to update mesh vertex properties via Python when mesh is influenced by armature
  -> Related: T19876 Changing vertex colors doesn’t work for objects parented to armatures (closed as duplicate)
  -> Related: T33462 UV map cant be ‘animated’ if mesh has vertexgroups or shape keys
  -> Related: T37125 Moving UV coordinates on objects with shape keys fails (can be closed as duplicate)
  -> A lot of potential is lost because of this
• T34061 Bones rotated ~160° flip normals of normal maps
  -> Related: T32383 Baked normal maps distort on rigged meshes (closed as duplicate)
  -> Makes armature deformation in some cases not an option
  -> Makes normal-mapped characters not an available option whatsoever
• T31876 Objects with more than one material-> Related: T35288 Collision and Touch Sensors don’t work properly
  -> Related: T38335 Raycast and replaceMesh
  -> Related: T34167 Game Engine Support material linked to object (not sure)
  -> Makes sensors incompatible with objects with more than one material
• T35917 Support parent relationship dynamics after restore
  -> Related: T19377 re-estabish dynamic object properties after unparenting doesn’t work
  -> There’s a workaround by parenting in game, but this makes (actual) hierarchies not visible in the Outliner
  -> Although I can’t think of a situation in which Dynamic objects are children

LibLoad-

Not Really a bug so much as a feature - Expose LOD distance calculated per frame by LOD.

@ BluePrintRandom: If you think a new feature would solve a lot of issues then refer to the task in the tracker. Also just saying ‘LibLoad’ is not enough. Please refer to the task in the tracker and clarify (if needed) why this is so important to you. Thanks.

Well, I can’t believe there are just a few who are enthusiastic about this. So, bumping this.

[sdfgeoff]

The fact is that most users of BGE are relatively new to game making, and as such, don’t run into these bugs.
The only ones I really care about are the libload ones.

[Raco]

I didn’t expect users to have bug requests when they’re not experienced with the BGE, but there’s more than a handful that are…

Anyway, I made this thread to establish the fact that the BGE still needs bug-fixing. And it’s not LibLoad/LibNew/LibFree alone. For example the 4th bug I mentioned earlier, which is present for more than two years now. It’s not doing the engine any good.

these are for me the most important bugs, because the start game from file logicbrick also has an chance on crashing the engine when loading a blend file.
this so far has been the only gamebreaking bug we have.

Is this ‘Start Game From File’ bug reported yet? Maybe you could give a link to the task description in the tracker?

I haven’t found a report, so I will try to make a .blend file to illustrate the problem.

I found this has a bigger chance of happening when using a previously loaded .blend, for example:
when starting the game you get a menu, after that when you go back to the menu there is a (big)chance that the engine crashes.
this happens a lot in the standalone blenderplayer

That would be great. Thanks.
