Explode (piece) that can be given a direction/speed

[knorke]

Usually Explode (piece) makes the piece fly of in some lame random direction.
From
void CUnitScript::Explode(int piece, int flags)
0.5f-gs->randFloat()) * 6.0f, 1.2f + gs->randFloat() * 5.0f, (0.5f - gs->randFloat()) * 6.0f

But the speed of the unit is also factored in and thus if you change unitspeed via MoveCtrl, you can basically direct what speed/direction the pieces fly:

Code: Select all

function headExplodeTest ()	
	local speed = 100
	local x,y,z=Spring.GetUnitPosition (unitID) --needed so unit does not bounce all over the place
	while (true) do
		for a = 1, 360, 10 do
			xs = math.sin (math.rad(a)) * speed
			zs = math.cos (math.rad(a)) * speed
			Spring.MoveCtrl.Enable (unitID)
			Spring.MoveCtrl.SetPhysics  (unitID, x,y,z, 
			xs, 0, zs,
			0, 0, 0)		
			Explode (head, SFX.FALL)
			--Spring.MoveCtrl.Disable (unitID) --doesnt seem to work
			Sleep (100)
		end
	end
end

Problem is, changing unit speed makes it go into that direction because physics. So atm I only got it to work with unmobile units, but eg for death animations it should be ok with mobile units. (dead units dont move unless journeywar)
Also works with SHATTER btw, the shards fly off in the same direction.

1)

Code: Select all

class CPieceProjectile: public CProjectile

3) ???
4) profit!

oh.
But to get a projectileID I need to enable WatchProjectile/Weapon (or whats it called) and I thought that was expensive?
Also what is the projectile/weapon DefID for exploded unit pieces?

To get piece projectile ID's you don't, because a certain developer has not yet added a watch-filter for them.

Also what is the projectile/weapon DefID for exploded unit pieces?

nil

proOwnerID seems to be unitID and GetProjectileName is the piece name. (was afraid that it would be nil or something silly)
cool cool except now it is almost too easy.
