Hi,

One guy ask in the forum about how to make a weapon system to use with newton vehicle.

I put the code here to help more people.

You need to the code work

1 - the newton's wdl includes in your script
2 - a weapon model to assign the code
3 - a bullet model (cam be any thing.)

You need change the code vertex number to your vertex model number.

If you use it, not forget to send me a gift

I hope you enjoy,

the code

Code:

//bullet code by Marcio Esper
//using NGD 1.51
// you need a gun entitie to set the bullet origen
//you need a bullet model
//examine the code, some things you can delet if i forget in the code 


entity* projetil;

var destino[6];
var origem[6];
var final [6];
var newtonImpulseRecord[8];

function baladata(material){
	
	var collisionType;
	var body;
	dll_handle = newtonHandle;
	
	body = NewtonGetBody (my);
	collisionType = my.collision_sph_box;
	body = NewtonAddMapEntity (my, collisionType);
	NewtonSetBodyMass (body, my.mass);
	NewtonSetBodyLinearDamp (body, my.linear_drag);
	NewtonSetBodyAngularDamp (body, my.angular_drag_x, my.angular_drag_y, my.angular_drag_z);
	NewtonSetBodyForceAndTorque (body, ApplyGravityForceEvent);
	NewtonSetBodyMaterial (body, material);
	NewtonSetBodyActiveState (body, my.start_active);
	vec_for_vertex(destino, torres, 130);
	vec_for_vertex(origem, torres, 78);
	//vec_diff (final,destino,origem); not need this
	
	
	//ENT_playSOUND (torres, bum, 100); - uncoment and make a sound if you need it
	
	
		       // gun end of tuble point
			newtonImpulseRecord[0] = destino.x;
			newtonImpulseRecord[1] = destino.y;
			newtonImpulseRecord[2] = destino.z;
			
			// origin of bullet (use to determone the direction of the impulse)
			newtonImpulseRecord[3] = origem.x;
			newtonImpulseRecord[4] = origem.y;
			newtonImpulseRecord[5] = origem.z;
			
			// copy the bullet mass - change it to more or less distance and damage
			newtonImpulseRecord[6] = 10000; 
			
			// copy the bullet speed - change like above
			newtonImpulseRecord[7] = 900;
			NewtonBodyAddImpulse (body, newtonImpulseRecord);

}



action bala{
	
	projetil =me;
	my.red=255;
	my.green=200;
	my.blue=100;
	my.lightrange = 400;

	my.health = 20;
	my.shape_factor = 0.9;
	my.start_active=1;
	baladata(wood_material);
	
}

Function tiro(){
	
	vec_for_vertex(temp, torres, 130); //get temp the position of vertex 
        ent_create("balabh.mdl", temp, bala); //you need a bullet model, in this case I use balabh.mdl, you can use a little box

	
}



on_mouse_left = tiro();

Sorry for the terrible English,

best regards,

I'm glad you posted this in this forum. It fires flawlessly but one question, is there a way for it to actually damage objects? Newton says objects take damage from impacts, but mine don't.

You can make it change the newtonScript2.wdl template.



best regards,

Marcio

Ok I'll give it a try. Thanks again for the code.
