Spring RTS Engine

CA needs to detect when shields are hit by projectiles if the shield behaviour is going to be improved. Params would at least need to be ShieldID, AttackerID, damage, collision position. The callin would need to be called even if a weapon has more damage than shield charge (ie it would pass through the shield). The callin should return whether the projectile should be destroyed or not.

+1, it would be cheaper than constantly checking the state of the Shields, for area shields.

You forgot the most important one, weaponID.

wouldn't it be better if it gave you the projectile object as well? then you could choose to do actions on that such as destroy, apply impulse, or modify it in other ways ?

I've not seen any Lua commands affecting projectiles, so no, you could not apply impulse to the projectile via Lua.

not with that attitude!

could make some lua projectile functions

(There are more than these.)

I stand corrected.

Spring.GetProjectilePosition(projectileID) -> px, py, pz
Spring.GetProjectileVelocity(projectileID) -> vx, vy, vz
Spring.SetProjectilePosition(projectileID, px, py, pz) -> nil
Spring.SetProjectileVelocity(projectileID, vx, vy, vz) -> nil
Spring.SetProjectileDetonate(projectileID) -> nil

Its usefull not just for gameplay but also for effects - we could spawn some nice ripples on shield surface or make completely customized shield visualisation.
