ZScript line trace visual aid

Post by **Nash** » Wed Aug 29, 2018 11:17 am

Debugging things with line tracing can be very frustrating. I propose a visual aid that visually draws the line so that we can actually see what the trace is doing. Unreal Engine 4 has this.

Yes, please. Testing is so annoying, being able to see traces would be amazing.

This sounds very useful; how do you think this should be implemented? Personally, I think a CVAR would be nice.

In Unreal Engine 4, it is a new parameter from the trace functions themselves so I'd roll with that. A CVar would be too inflexible because you can't choose which trace to draw, and there might be a lot in the scene. :)

Graphics-wise, I'm imagining a 2D line drawn on the 2D canvas, or perhaps a quad spawned and stretched in the world. I wouldn't know what's best here; will leave that to the engine gods. :)

Hi, I know this is an old thread but if anyone is looking for a line trace visualizer, I wrote one in this thread.
