I have a issue with a knife entity. I have "Remove 1" flag in the entity header and when the enemy throws the knife it will be removed on hit as expected but when a player throws the same weapon it will fly through all enemies.  I found a work around using followanim & followcond but this seems to be a engine bug has anyone else had this issue ?

weapon entity:
Code: 
name		Knife_Throw
type		none
antigravity	100
remove		1
shadow		0
candamage	enemy player
offscreenkill	200
no_adjust_base  0
subject_to_wall	1
subject_to_platform 1
subject_to_hole 1
subject_to_obstacle 1

Normally this has to do with how you do spawn/throw the knife. It normally works if you spawn it with "custknife" and "throwframe" but it does not work if you spawn it with script. Because when you spawn it with script the engine obviously does not recognize it as a "knife" so the remove command can't work. So, it's not a bug in such case.

Hi msmalik681!

I have an alternative way to throw weapons and "Remove 1" works fine both for players and enemies. I don't use "throwframe" to throw weapons because in the scripted form I can adjust the x,y,z position/velocity freely and other properties too. The the "throwframe" command is here only for change from weapon models to default models, the scripted way to do this is bad. And the antiwall script is here because if the entity is too close from walls in x or z axis, the throwned weapon will disappear.

I hope this can help you. Here is the code:

	void vShot;
	
	if(Direction == 0){ //Is entity facing left?                  
		dx = -dx; //Reverse X direction to match facing
	}

	vShot = projectile(weapon, x+dx, z+dz, y+dy, Direction, 0, 0, 0); //Generate entity using "projectile", not "spawn"
	changeentityproperty(vShot, "velocity", Vx, Vz, Vy);
	changeentityproperty(vShot, "speed", Vx); //"X" Speed control
	changeentityproperty(vShot, "parent", self); //Set to parent
	changeentityproperty(vShot, "candamage", candamage); //Copy "self" candamage property
	changeentityproperty(vShot, "subject_to_platform", 0); //Set subject_to_platform to 0
	
	return vShot;
}
