Hi,:)

The cores material it is just a material effect for the bullet, you can remove it safely.

Code:

---

action bala{
	
	projetil =me;
	//my.material = cores;
	my.red=255;
	my.green=200;
	my.blue=100;
	my.lightrange = 400; //it is for light, change the range to your enviroment looks bether
	my.light=on;
	my.mass =10;
	my.health = 20;
	my.shape_factor = 0.9;
	my.start_active=1;
	baladata(wood_material);
	
}

best regards,
