Is there a way to draw certain vectors in space during play to see how they behave?

I’d like to use that for debugging and testing.

I don’t think so, but it would be awesome if you could plug a vector into a print node to see the vector drawn in the game. Of course the issue would be that a vector by itself doesn’t actually have a 3d start and end point, just a certain number of lengths (eg 3 for a vector3), so it isn’t exactly clear where onscreen a vector would be drawn.

@Quartz as it is simple to set, efficient to observe what’s happening, I used simple cones of different colors to visualize vectors orientations when for example it’s necessary to follow effects of qaternions/vectors change inside armatures… then after some use, I replaced them with simple planes object … more efficient to observe vector orientations.

In the past I’ve just created two cube objects with an emission shader and, on update, I put one at the vector start location, and the other at the end location. A logic node for it would be really cool.

Thanks for your answers, I ended up using objects scaled or moved to visualize the vectors on real time, thoose are nice solutions too.

Just wanted to know if a specialized tool already existed.
