Good day.
I have a problem with animation and I think that the matter is in engine.
The problem:
When I have about 10 same vertex animated models on screen there frames are changing incorrectly some times. I use template scripts. I make even simpler animation function:
if(my._health<=0){my.frame=13;}
else{my.frame=1;};
And the wild frame changes was again: some alive models sometimes look as dead (frame 13) and some dead models look as healthy (frame 1).
This is not happening when I off d3d_transform: d3d_transform = off;

So why this bug happening when d3d_transform = on?

Instead of naming it as "frame 1" for your stand position and "frame 13" as your death position, name them in a more standard way such as "stand 1" for the first animation frame for the stand action or "death 1" for the first animation frame of the death sequence or "bored 1" for the long animation when the character remains in one spot for a long time.

ShadowsBook, why don't you update your version of Pro to 6.31.4? I can see the reason that you want to develop games that use DirectX 8.1 but my suggestion is to try 6.31.4.

The frames have names "stand 1" and "death 1".
I use "frame=1" and "frame=13" only for direct access to model frames.
Normally, I use standard template “actor_adv_anim2” for animation.

Well, 3 weaks ago, when I update my 3dgs to 6.31.4 (that works with DirectX 9), my game start bugging even more: decoration sprites start to flipping very ugly, the FPS down very greatly and so on (my card is NVIDIA GeForce 4MX 440 and I planning my game to work even with cards as my own).
