[1.7.2]GL11 Rendering Crash

[SoBiohazardous]

So, i'm trying to render something above the players head. Here is my render code in my tick method:

if(player.inventory.getCurrentItem() != EMDItemManager.hangGlider.getContainerItem(null))
     {
         GL11.glPushMatrix();
     ModelHangGlider m = new ModelHangGlider();
     Minecraft.getMinecraft().getTextureManager().bindTexture(new ResourceLocation(MAssetManager.getEMDTexture("textures/misc/hangGlider.png")));
     int tick = 0;
     tick++;
     float rotateYaw = EMDEventHandler.interpolateRotation(player.prevRotationYaw, player.rotationYaw, tick);
     GL11.glRotatef(rotateYaw, 0, -1, 0);
     GL11.glRotatef(180F, 0, 0, 1);
     GL11.glTranslatef(0, 0, -0.5F);
     m.render(0.0625F);
     GL11.glPopMatrix();
     }

 

This is my crash:

The line number points to GL11.glPushMatrix();

I'm not sure why I am getting this crash, considering this worked in 1.6.4. Please note that my tick method is using PlayerTickEvent.

Any help would be greatly appreciated

Hi

 

It appears that your rendering code is running on the server thread.

 

You need to check for the correct side in PlayerTickEvent.

Thanks, it no longer crashes.
