Render Image over other players

[Jaffaaaaa]

I've tried to look for help on how to just render an image over other players but every time I look for threads I can only find examples of people editing their own player's movement etc.

Any help would be appreciated.

What exactly do you mean by this?

Literally just render a 2D picture over a player. Not a reskin or anything. Just to draw an image on a player (and scale to how big the player is)

I think the easiest way to do this would be through the Tessellator, by drawing a textured quad in front of the player in the 3D world. You would have to keep the square pointing towards the player in order for it to look good.

Steps for using the Tessellator can be found in my answer here.

Information on how the Tessellator works in general can be found here, but the exact steps are outdated, so refer to the above link for that.

A code example can be found here, but don't copy the stuff directly, because I got the translation code wrong (explained in the answer I posted).

 

This is actually kind of complicated, because there is no knowledge (at least not to my knowledge) of what is being rendered on the screen that you can hook into. No "rendering a player here" information for you to use. That means you either need to draw a 2D picture at the screen (x, y) of the 3D->2D projection of the player onto the screen, or do the above. I'm pretty sure the above is the way to go.

Subscribe to RenderPlayeEvent.Post and do your rendering there. The render position of the player is passed in via the event.

Presumably that's still a 3D coordinate, in relation to the screen view, right? Or is it actually the 2D window coordinate? That doesn't seem as useful though, since you'd lose depth information, so I'd guess the first (not that my guess is very important, lol).

Since the rendering of the player is done by OpenGL in a 3D space, the coordinate is a 3D coordinate in regards to the OpenGL rendering position (in relation to the screen view).
