TE BEAMSPRITE

A beam with a sprite at the end.

It appears to be completely useless since it's only visible for a single frame and there is no way to increase its life time. Please, someone correct me if I'm wrong.

TE_BEAMSPRITE

void te_beamsprite(Vector start, Vector end,
	string beamSprite="sprites/laserbeam.spr", 
	string endSprite="sprites/glow01.spr",
	NetworkMessageDest msgType=MSG_BROADCAST, edict_t@ dest=null)
{
	NetworkMessage m(msgType, NetworkMessages::SVC_TEMPENTITY, dest);
	m.WriteByte(TE_BEAMSPRITE);
	m.WriteCoord(start.x);
	m.WriteCoord(start.y);
	m.WriteCoord(start.z);
	m.WriteCoord(end.x);
	m.WriteCoord(end.y);
	m.WriteCoord(end.z);
	m.WriteShort(g_EngineFuncs.ModelIndex(beamSprite));
	m.WriteShort(g_EngineFuncs.ModelIndex(endSprite));
	m.End();
}

Vector	start	Starting position of the beam
Vector	end	End position of the beam
string	beamSprite	Sprite used to display the beam
string	endSprite	Additive sprite drawn at the end of the beam
