About weapons implementation
Loading weapons is easy, just load weapons.dat, and their models, and that's pretty much it.
What is difficult, is to integrate weapons with animations.
We need the following functionality:
-
When player aims, he needs to switch to another anim, and he needs to lean his head (how to do this, is there a separate anim for this ?). - Found the anims that were needed.
-
When player aims, his head and hands should rotate in that direction (including up and down), so we would need to somehow rotate spine or something
-
When player has a weapon in his hand, the weapon should be attached to fingers (maybe with a little adjustment for fingers) - this way player can do all anims (jump, run, etc), and weapon will remain on the proper place. This should only be done for specific anims.
-
There are cases when we need to play 2 anims at the same time. Examples: reloading a weapon, aim and move at the same time. How to do this ? Tried with anim blending, but it looked ugly. Try avatar mask ?
Each weapon has it's own anim group. So, anims will be played based on what weapon is held.
But how to determine position of weapon ? Each weapon has firing offset, and aiming offset (maybe this is actually the position of weapon). - This can be done by testing.
Where to place hands ? There is nothing in weapons.dat saying about this. Is it hardcoded ? Or shall we just play weaponaim anim, and somehow adjust hands/fingers based on type of the weapon (or his aim offset) ? - Looks like that this is handled by anim.
These are the useful parameters in weapons.dat :
- fire offset (this could be just the location of bullet when it's fired ?)
- aim offset (this could be position of weapon when it's held, or position of where the other hand should be ?)
- anim group
TODO
-
play separate anim for tec9 ?
-
let aim anim to control head (or spine ?), in order to better simulate bullet firing ?
-
improve aiming with AIMWITHARM weapons - upper arm should follow right vector of aiming, when aiming to side
-
reloading
-
when lerping upper arm transform toward player forward vector, arm is going on the opposite side - it seems that it depends on world rotation of player
-
spine should be rotated locally, not globally ? - some models have different rotation of spine in the idle anim, which means that their spine will not look at the same place - possible solution would be to play the same idle anim on all models
-
right after the model is loaded, reset model state - it's already done ?
-
rotate the pelvis instead of spine (because thighs look ugly)
-
rotate neck instead of spine, when following direction of aiming
-
play separate anim for: minigun and flame thrower,
Damage system
-
particles on place of hit
-
display inflicted damage as on-screen message
-
die animation ; ped needs to have IsDead bool variable - code has to be adapted ;
-
we need to raycast against ped mesh, not capsule collider ; also need to detect which part of body was hit
-
adapt vehicles to damage system
-
decals
