[−][src]Module vxdraw::debtri
Methods and types to control debug triangles
A debug triangle is a triangle that ignores all global transformations and is always shown on the screen (except when a triangle's coordinates are outside the screen). Debug triangles are meant to be used to quickly find out if a state has been reached (for instance, change the color of a debug triangle if collision is detected, or rotate a debug triangle while loading).
Debug triangles always ignore all layers, and are always shown on top of the entire scene.
See debtri::Debtri for all operations supported on debug triangles.
