Basically, me and a group are working on a game for our university class this term and one of the ideas is a teleport gun where if you target certain things it lets you swap places with them. i am building this off the FPS starter kit, but im having serious issues with c_trace. What is the best way to go about this?

the best way would be to describe what problems EXACTLY you have with c_trace...

basically I have no idea how it works. i tried a few different things, for instance i was going to give all the objects you can switch with a certain texture, so i kept having c_trace check the texture of objects but no matter what i did it always returned back the texture BELOW my character, no matter if i had it c_tracing from x, y, or z.

If I were making such a weapon, I'd use entities and then use WED to make the objects SKILLn (where 'n' is whatever skill number you want) 9. (also arbitrary).

Then, I'd use c_trace (as I said before, use AUM 59 for reference) to trace from the weapon to 10000 quants forward. If the ray hits an object and you.skilln == 9 (i.e. a vase you placed on the floor and set its skilln to 9), store the objects position in a variable, store the players current position in a variable, then swap them.

Sure its a little more complicated than that, and if I coded it I imagine it would take me the better part of a day (so I won't ) Sorry I can't be of more help.

my problem seems to be that when i use c_trace it is tracing from below my character no matter what direction i tell it. at this point i have no weapon scripts actually in the game, i took out the base ones while i worked on things and i could add them back.

sorry im a total newb at this, heh, i wasnt suppose to be the programmer on the team but ours decided to not show up and not help us, so someone had to do it =\

What model are you using for the player? If you made it yourself did you ensure its origin is not under its feet or something silly like that?

Also, post a snippet that contains your c_trace so people can better understand the issue.

Here, this may help (I took the idea from AUM 59 for you)
Code:

---

var TraceCoords;

on_mouse_left=TeleportGun();

function TeleportGun()
{
	vec_set(TraceCoords.x, vector(10000, 0, 0)); //shoots 10000 quants
	vec_rotate(TraceCoords.x, player.pan); //shoots in the direction of the player
	c_trace(player.x, TraceCoords.x, ignore_me | ignore_passable | activate_shoot);
	if (you.skilln==9)
	{
		...put teleport stuff here
	}
} 

---

Now that is the general idea, and I *think* it may work but I didn't test it because I just don't have time (and obviously there is no teleport code there )

Good luck.

vec_rotate(TraceCoords.x, player.pan); shouldn't that be camera.pan or ...

My function looks like:

function TeleportGun()
{
c_trace(my.x,target_pos.x,ignore_me);

if(you) // An entity was hit?
{
vec_set(temp.x,my.x); // Store position of the player
vec_set(my.x,you.x); // Setting player to hitten entity
vec_set(you.x,temp.x); // Setting you to the stored player position
}
}




and then on right mouse click im calling the function. basically nothing happens with that code, and with the code you put there i keep getting empty pointer errors when i put the teleport code in and try it.

i made the model, but the origin is in the middle and its facing the right way.

and when i use your code i get a overun error because of skilln==9

and i did set the flags to that on the object, so im not sure why
