Animate shooting effect by code

Is there any engine that ignores the shooting effect from the MDL and makes the shooting effect by code, like bobbing, for example? Q3 did that and looked good.

What do you mean by "shooting effect"? If you mean the muzzle-flash animation then the answer is no, because it's part of the MDL. You'd need a replacement MDL for it.

The movement of the model, not the muzzle flash.

That's done in view.c on the engine, not QuakeC.

The model movement itself is also part of the MDL animation, nothing to do with code (although code does select which frames to use).

As i said, i wanted to ignore MDL animation. I'm using static models and wanted to animate them through code, like Q3 did.

q3 did that by cgame (Client-side game code)

quake doesn't have a cgame - it's either engine code or serverside progs.dat
