I'm relatively new to Jitter and I have big problems with accomplishing my project. Here is what i want to do:

I have a background picture of the size 1440x720 on it is a little ant (180x180) as soon as it gets triggered it runs out of the picture. It should always "run" in the direction its head is facing. I thought of accomplishing it like this.

ji.rota with a random angle. With that angel and sin and cos I calculate the movement and move the video with usedstdimstart and usedstsimend in a jit.matrix object. The movement works fine but I doesn't take the rotation from jit.rota. I'm not even sure if this is possible! Is there a better way to do it?!

I'm searching and searching, but I'm not sure what I should be searching for is the jit.gl.videoplane a possibilty and is there any further explanation than the integrated tutorials cause they didn't help me at all with the videoplane object.

Have a look at your Max5 folder. there are some examples with jit.gl.videoplane under "examples/jitter-examples/render"

Thank you very much, I think this will be a good start. What I don't get tough is the positioning and scaling scale. Is this defined through Open GL? Is the total Screen then from -1 to +1? And if I want to do a movement, which changes the position via a counter I have to do a differentiation with > and

I really don't want to ask you such basic question, but I don't seem to find good additional Information on the web or in the reference. Or should I be looking in OpenGL books?

postion and scale in opengl are relative coordinates (meaning relative to the size of the context window).

if you simply want to do 2D placement of videoplanes, you should probably use one of the orthographic projection modes (@ortho 1/2 on your gl.render object).

see if this basic example helps you out:
