Moving an object using script

by Infinitum3D · in Torque Game Engine · 07/02/2007 (3:08 pm) · 5 replies

Can the rotation or position or location of a shape be changed using script?

I have a simple cube that I'm using for a door. I want it to move onCollision. I've seen resources with calls to the server and source changes, but a simple script should work.

It seems very easy.

If
player collides with door
then
door position = new door position

Here's my door.cs with datablock and function

datablock StaticShapeData(DoorItem)
{
category = "Doors";
shapeFile = "~/data/shapes/doors/door.dts";
};

//--create the door in-game
new DoorItem()
{
dataBlock = "DoorItem";
position = "222.2 -727.3 108.1";
rotation = "0 0 1 130";
scale = ".2 .2 .17";
};


//--collision detection to open door
function DoorItem::onCollision(%this, %obj, %col)
{
if(%col.getClassName() $= "Player")
{
%client = %col.client;
echo("Player collides with door!");
//%obj.position = ("222.2 -727.3 110");
//%DoorItem.rotation = "0 0 1 40"
//%obj.location = ("222.2 -727.3 111")
//%obj.delete();
%DoorItem.position = "222.2 -727.3 111";
echo("Door raises!");
}
}



Everything works EXCEPT the position doesn't change. It compiles into a .dso, my echos show up in the console, but the door does NOT change postion. You can see where I've commented out many attempts. I've tried this using %location, rotation, position, etc. Everything I could think of.

Is it a simple syntax error, or are doors really that difficult to code. All I want in for a cube to change it's location on collision. I can get it to go away using %obj.delete(); so I know I can manipulate it.

Thanks,
Tony

Use the setPosition() method:

%DoorItem.setPosition("222.2 -727.3 111");

Thanks Peter! Can setPosition affect rotation also?

%DoorItem.setPosition("222.2 -727.3 111 0 0 1 180");

This works.

- Also I think you can trigger an animation instead of moving the door.

- Another thing... to get it to show up in the world editor I think you just need to use DoorItem::onAdd and do the new DoorItem() stuff in there... take a look at the fps.starter and I think there's a StaticShape::onAdd that will add anything you want by default (might be a file called staticshape.cs ?).
