This example shows how to trace a line with primitives on GameMaker Studio 2.

How it works:

The current position of the mouse is inserted in two lists (x and y). The lists have a limit of points that can contain, if this limit is reached, the last items of the lists are removed.

To draw the line we use primitives with the pr_trianglestrip mode, so after creating the first triangle with 3 vertices, each new vertex adds a new triangle that is formed based on the last two vertices.

If you have any comments or suggestions, please, let me know.

Enjoy :)
