Draw a cube above an entity


Kloonder

Recommended Posts

So I am wondering if it is possible to draw a cube above an entity. No matter what kind of entity it is.

 

Where should I start, with event handler? Because ther isn't an actual event for every entity rendered, is it?

 

public static void drawCube(double x, double y, double z) {
        GL11.glBegin(GL11.GL_QUADS);
        GL11.glColor3f(0.5f, 0.5f, 0.0f);
        GL11.glVertex3f(0.5f, 0.5f, -0.5f);
        GL11.glVertex3f(-0.5f, 0.5f, -0.5f);
        GL11.glVertex3f(-0.5f, 0.5f, 0.5f);
        GL11.glVertex3f(0.5f, 0.5f, 0.5f);

        GL11.glColor3f(0.5f, 0.5f, 0.0f);
        GL11.glVertex3f(0.5f, -0.5f, 0.5f);
        GL11.glVertex3f(-0.5f, -0.5f, 0.5f);
        GL11.glVertex3f(-0.5f, -0.5f, -0.5f);
        GL11.glVertex3f(0.5f, -0.5f, -0.5f);

        GL11.glColor3f(0.5f, 0.0f, 0.0f);
        GL11.glVertex3f(0.5f, 0.5f, 0.5f);
        GL11.glVertex3f(-0.5f, 0.5f, 0.5f);
        GL11.glVertex3f(-0.5f, -0.5f, 0.5f);
        GL11.glVertex3f(0.5f, -0.5f, 0.5f);

        GL11.glColor3f(0.5f, 0.5f, 0.0f);
        GL11.glVertex3f(0.5f, -0.5f, -0.5f);
        GL11.glVertex3f(-0.5f, -0.5f, -0.5f);
        GL11.glVertex3f(-0.5f, 0.5f, -0.5f);
        GL11.glVertex3f(0.5f, 0.5f, -0.5f);

        GL11.glColor3f(0.0f, 0.0f, 0.5f);
        GL11.glVertex3f(-0.5f, 0.5f, 0.5f);
        GL11.glVertex3f(-0.5f, 0.5f, -0.5f);
        GL11.glVertex3f(-0.5f, -0.5f, -0.5f);
        GL11.glVertex3f(-0.5f, -0.5f, 0.5f);

        GL11.glColor3f(0.5f, 0.0f, 0.5f);
        GL11.glVertex3f(0.5f, 0.5f, -0.5f);
        GL11.glVertex3f(0.5f, 0.5f, 0.5f);
        GL11.glVertex3f(0.5f, -0.5f, 0.5f);
        GL11.glVertex3f(0.5f, -0.5f, -0.5f);

        GL11.glEnd();

        GL11.glTranslated(x, y, z);

I'd take a look at how armor is rendered, then just use that to produce the cube over the entities head. I know as of 1.8, Minecraft uses a "layered" armor system. But, I have not been able to figure out how to utilize it correctly. :/

But how should that work on an EntityItem? I don't think armor is implemented for an EntityItem.

I now figured out how I wanna do it. That way

 

@SubscribeEvent
    public void renderGameOverlayEvent(RenderWorldLastEvent event) {
        EntityPlayer player = mc.thePlayer;
        if (getItemPlayerIsLookingAt(player) != null) {
            if (getItemPlayerIsLookingAt(player) instanceof EntityItem) {
                EntityItem item = (EntityItem) getItemPlayerIsLookingAt(player);
                RenderHelper.drawCube(item.posX, item.posY, item.posZ);
            }
        }
    }

 

But my problem is, no matter what I try, the cube will always stick to my feet

If anyone knows how to move that cube away, feel free to leave a reply

 

THe code for rendering the block is in my first post

I think you have to translate the cube to the Entity position.

Don't PM me with questions. They will be ignored! Make a thread on the appropriate board for support.

1.7.10 and older versions of Minecraft are no longer supported due to it's age! Update to the latest version for support.

More specifically:

 

        GL11.glEnd();

 

        GL11.glTranslated(x, y, z);

 

I love how you add a translation after you finish drawing.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

 

DO NOT PM ME WITH PROBLEMS. No help will be given.
