Hello.

I need to draw my texture on first person view screen in point relative to my 3D-item model when it renders.

What i need to do?

Well... Your rendering your 3D item aren't you?

 

Try using those coordinates that you are using there.

i trying to use coordinates of the player and adding some float to x,y,z. But it draws in wrong position.

Depending on what you want to do,

func_147906_a

of

net.minecraft.client.renderer.entity.Render

(in 1.7.10 anyway) might inspire you. As far as I can see, that renders a string above an entity, if it is close enough to the player.

 

The method is probably not immediately useful to you unless you are specifically trying to draw a string above an entity, but the contents of the method should give you an idea of how Minecraft deals with rendering screen-space overlays of world-space objects.

Okay... So you are wanting to draw a 2D texture to the screen? Fair enough.

 

Take a look at RenderGameOverlayEvent.PRE

 

If you only want the texture to show while your item is being held, you can make a check to see if the player's current held item is an instance of your special item and then do your drawing.

Take a look at RenderGameOverlayEvent.PRE

 

That seems rather more useful, yes. Forgive me for referencing vanilla when there is a very relevant Forge event; I am just now getting into modding with Forge.

Thank you!

hm....... i must use drawTexturedModalRect, right?

i have create a class:

public class HookGui {

@ForgeSubscribe
public void render(RenderGameOverlayEvent.Pre event){
    if(event.type == ElementType.CROSSHAIRS){
        GL11.glPushMatrix();
        //GL11.glTranslatef(0.0F, -50.0F, 0.0F); // for test
    }
}

@ForgeSubscribe
public void render(RenderGameOverlayEvent.Post event){
    if(event.type == ElementType.CROSSHAIRS){
        GL11.glPopMatrix();
    }
}
}

but how to draw texture?

That is NOT how OpenGL works... Please go learn

 

Personally, I use the tessellator to draw things in GUI's... So...
