Render a player as ghost-like

[Reflxction]

Hello. Over the past days I've been trying to find a way to render players to look transparent, just like when they're invisible with the see invisible friends scoreboard tag. I looked around the game code a lot and really couldn't find anything that seemed to be what I want. I probably didn't search enough, so can you possibly help me in my process or tell me where the best place to look at is?

 

Regards

Cancel the render player event, that's the start. You're going to have to access the shader code and write a shader in GLSL to render the player as transparent. Then you're going to have to apply the shader and render the player yourself don't forget to unbind the shader program when you're done.

You might not actually need to render everything yourself, if there’s a playerRenderEvent.Pre you could probably just enable blend & do a blend function. Then disable blend again once everything is done rendering

Thanks for the help! I'll try when I get on my computer and report back.

Update: Apparently it was much simpler than I thought. 

@SubscribeEvent
public void onRenderPlayer(RenderPlayerEvent.Pre event) {
    GlStateManager.enableBlendProfile(GlStateManager.Profile.TRANSPARENT_MODEL);
}

(Result below) 

Thanks for the help!

Don't forget to disable the transparency when you're done (in RenderPlayerEvent.Post).
