Haxball Headless get in specific area and an other question

[paq]

Hello,
I want to program in headless that after X seconds after the game start all users get kicked who are outside of an area, for example a circle.
How can I do this?
Then I saw in the headless wiki something called "disc", what are those/is that and what does "disc" stand for?

Thank you

Discs are round game physics objects (players, ball, goal posts, ...).

For your problem, you need to compare player position to the area you want them to be in. For a rectangle, you just check if x/y coordinates are >= x_min/y_min and <= x_max/y_max, for a circle you check distance from the center of that circle.

Hey thanks for the answerr Do you maybe have an example on how that could look like regarding the rectangle?
