Finding item position?
by Dracola · in Torque Game Engine · 06/29/2005 (11:03 am) · 14 replies
Can you return an Items position? heres my code.
function mine2::onCollision(%this)
{
%pos = %this.position;
%p = new (projectile)()
{
dataBlock = mineexploder;
initialVelocity = 0;
initialposition = %pos;
client = %this.myclient;
};
MissionCleanup.add(%p);
echo("kabomm");
echo(%pos);
}
the echo for %pos comes up blank and it creates projectiles in random locations. This is the last step to the resource I want to create and its killing me. I've also tried %this.getposition(); and it doesn't like that any help.

Don't take me as knowing anything... but i've seen getTransform used to get position before.

Yeah I thought it only worked in C++ but I've also seen it used in earlier scripting and thought it might work. GetTransform might work I think that might be what was used to find spawn points.

Just make a console method that returns getPosition() ... Easy as pie.

I don't have much experience with console commands what exactly would that look like.

you only need to use gettransform() if you need the position and rotation.

%pos=%this.getposition();you only need to use gettransform() if you need the position and rotation.

He said he already tried that. He didn't try getPosition() though.

Actually his original post says he tried getposition() and it "doesnt like that" which is strange because, as far as i know, both methods should work. something else must be wrong.

%pos = %this.getposition();
and got console errors which I could post if anybody wants

Just speculating here. Feel free to tell me Im wrong.
Post the errors...

I don;t have code in front of me... but doesnt an onCollision method usually have more hten %this in it ? I thought it had a %obj and %col... Which would allow you to use %obj which is generally the object that is being collided against...Just speculating here. Feel free to tell me Im wrong.
Post the errors...

onCollision(%this, %obj, %col, %vec, %speed)
this is for the player object. i dont believe this is the problem but this would probably make what youre doing alot easier. i just realized something. according to mr. finney, the oncollision function is different for a projectile object:
onCollision(%this, %obj, %col, %fade, %pos, %normal)
I suppose %pos is the point of impact and %normal is the normal of the surface the projectile is incident on, but what is %fade?

mine2::onCollision(%this,%obj,%col)
{
%pos = %obj.getPosition();
..
}

Try this mine2::onCollision(%this,%obj,%col)
{
%pos = %obj.getPosition();
..
}

EDIT:
Jst a note that getPosition() works in the C++ code... as I used it to do localized precipitation blocks.
