[1.7.2] HUD overlay won't render.

[Zebo1]

My mod implements a halo style gui for minecraft. However the methods I used wont render the image ingame.

 

Im using the exact same method used by the pumpkin blur.

 

The code calls the method (Which ive tested by putting a system.out.println("test") in the method). T

 

he the program also seems to find the image file. (Ive tested it by using an incorrect image location and it responds with the missing image error)

 

So im not sure what time doing wrong.

 

(I know my code has a lot of unused import, im going to clean those up once this issue is fixed)

You should be using the RenderGameOverlay event to render overlays, not a tick event. Also, don't create a new HaloRender every single tick; it only needs to be done once.

 

Check the wiki tutorial for more about rendering game overlays; it's for 1.6, but still pertinent in 1.7.

thanks for the help! its working now!
