Description

Hey there,

Please see attached project. Resetting the scissor via a struct received from gpu_get_scissor is not working. I did it exactly in the way as you write in the manuals at https://manual.gamemaker.io/monthly/en/#t=GameMaker_Language%2FGML_Reference%2FDrawing%2FGPU_Control%2Fgpu_set_scissor.htm

In the project you find an object ScissorBug. Look at the draw event, I documented each step.

kind regards, Gris

• Just run the project an look at the console
• See the Draw event of the ScissorBug in the project to the see the bug and the workaround

The new bug reporting tool does not let me edit my own posts, as I am no longer the author, so I have to put it as a reply here.

To make clear, what's wrong:

Please do NOT treat this as a "Documentation Bug" - it's a runner bug

(The documentation is fine - it should work, as described in the docs)

// THIS IS A COPY FROM THE MANUAL - IT DOES NOT WORK
var _scissor = gpu_get_scissor();
gpu_set_scissor(200, 200, 600, 600);
draw_self();
gpu_set_scissor(_scissor);    // <-- Here is the bug, it *should* work

// THIS WORKS
var _scissor = gpu_get_scissor();
gpu_set_scissor(200, 200, 600, 600);
draw_self();
gpu_set_scissor(_scissor.x, _scissor.y, _scissor.w, _scissor.h );   // <-- This works
