Moving Shapes Smoothly

by Dustin Williams · in Torque Game Engine · 12/07/2004 (11:40 am) · 7 replies

I want to use a while loop to move a shape. How do I do this? I know that I can use a getTransform/setTransform thing, but I don't know how to put this into a while loop. In 3DGS's WDL (A6) you did something like this:

while(1) {
object.x += 1;
wait(1);
}

the function wait waits one frame. Is there such a function in Torque? How the hell do simple frame-by-frame movement?

Thanks!

The "simple" way is to do some C++ code that will do interpolation and updates on the object. It's not quite as simple as the A6 approach, but you get a lot more control over what's going on.

What sort of simple motion do you want to acheive? There are a lot of resources out there and in the engine; it's possible somebody else already solved your problem.

I want to us an equation to launch a cannon ball. I have looked around for resources, but I still don't understand how I'd do this in a while loop. Should I do this in C++? How do I do this C++ or script?

The Projectile class supports "ballicstic" trajectories (ie...an arc like a cannon ball). You can make a cannonball work without a loop at all...just create a type of gun that shoots a type of Projectile that has the "ballistic" flag set to true in the datablock.

That works. But I'm creating a physics simulation and I would like to write the code that controls the ball myself (it's for a science fair project). How would I do that?

Replace the ballistics code with your own code.

Where is the ballistics code?
