I have a model of a car, i want it to move about a predefined route over and over. Now i have read about using Paths to be the way forward. This is what i have done:

clicked Add path and then used vertex move to draw out the area to follow, then i assigned the model of my car to the path in the properties path menu.


Now i am told i need a script to get it to follow it. any ideas on how to do this?

After looking in the manual i found this but not sure if its relevant:

// move along a path loop
// uses _FORCE, _MOVEMODE
action patrol_path
{
// attach entity to nearest path
result = path_scan(me,my.x,my.pan,vector(360,180,1000);
if (result == 0) { return; } // no path found

// find first waypoint
var node = 1; // start at first node
path_nodepos(my,node,my._TARGET_X);

while (my._MOVEMODE)
{
// find direction
result = vec_to_angle(angle,vec_diff(temp,my._TARGET_X,my.x));

// near target? Find next waypoint of the path
if (result < 25) {
node = path_nextnode(my,node,1);
path_nodepos(my,node,my._TARGET_X);
}

// turn and walk towards target
actor_turnto(angle.PAN);
actor_moveahead(MY._FORCE);
wait(1);
}
}



I have never really done any scripting in this before so please bear with me :-)


cheers

sorry i couldn't help you via email, paths are hard for me as well...

thanks any way buddy :-)

Try this:
Code:

---

//skill1: TurnSpeed 10
//skill2: MoveSpeed 10
action patrol_path()
{
	// attach entity to nearest path
	result = path_scan(me,my.x,my.pan,vector(360,180,1000);
	if (result == 0) { return; } // no path found
	
	var NodePos[3];

	// find first waypoint
	var node = 1; // start at first node
	path_getnode(my,node,NodePos,NULL);
	
	var angle[3];
	
	var Gravity;
	
	while (1)
	{
		// find direction
		result = vec_to_angle(angle,vec_diff(temp,NodePos,my.x));

		// near target? Find next waypoint of the path
		if (result < 25)
		{
			node = path_nextnode(my,node,1);
			path_getnode(my,node,NodePos,NULL);
		}
		
		my.skill21 = c_trace(my.x,vector(0,0,-10000),use_box|ignore_me|ignore_passents|ignore_passable);
		if(my.skill21 > 5)
		{
			Gravity -= time_step;
		}else
		{
			if(my.skill21 < 0)
			{
				Gravity += time_step;
			}else
			{
				Gravity = 0;
			}
		}
 
		// turn and walk towards target
		my.pan += ((angle.pan > my.pan)-(angle.pan < my.pan))*time_step*my.TurnSpeed;
		c_move(me,vector(my.MoveSpeed*time_step,0,Gravity),nullvector,glide|ignore_passents|ignore_passable);
		
		wait(1);
	}
}

Add it to the bottom of your mainscript file.
Place the model into your level, next to the path and give the patrol_path action to it.

If you get any errors please post them and I will try to fix it, cause I´m to lazy to create my own testlevel (which means, that I haven´t tested the script).

Thanks very much for your assistance buddy!

I found a very useful web site which has helped me to solve the problem i faced

i tried the above code but found this error which i have screen shotted for you.

Have a good day ppl and i hope to post the game up online sometime so you can see what was achieved of it, peace out x
