ItemTooltipEvent - Rendering Textured Icons

[Bedrock_Miner]

Hello Everyone!

 

I want to make the vanilla Items (and others) showing a small Icon when you hover over them. But with the ItemTooltipEvent, I don't get the required Objects to do this. I need a gui object to call drawTexturedModalRect.

 

How can I get this object? Or is there another way?

 

Thanks in advance!

Thank you!

But I now need to know, where the tooltip is rendered to adjust the position of the Icons. How can I find this out?

Actually I was inspired by thaumcraft...

 

But the problem is, that Azanor didn't made his code publicy available.

I now solved it... To be honest, it's very easy.

 

ScaledResolution scaledresolution = new ScaledResolution(mc.gameSettings, mc.displayWidth, mc.displayHeight);

int x = Mouse.getEventX() / scaledresolution.getScaleFactor();
int y = (mc.displayHeight - Mouse.getEventY()) / scaledresolution.getScaleFactor();

Well, I now need to render some text showed on my rendered picture. The problem is, that the zLevel setting seems not to work, because the text is rendered under the items although the zLevel is set to 300.

 

How can I solve this problem?

In the ItemTooltipEvent I first create a Gui object. Then I set the zLevel to 300 and draw some textured rectangles (drawTexturedModalRect). Then I call the drawString method of the gui object with the zLevel still set to 300, but the text is rendered below the previous drawn picture and even below the Items in the container.

The drawString method just draws the pictures of the text, right? So why isn't it influenced by the zLevel? Or how can you do this?

This here is the code to render a single char:

GL11.glTexCoord2f(f / 128.0F, f1 / 128.0F);
        GL11.glVertex3f(this.posX + f2, this.posY, 0.0F);
        GL11.glTexCoord2f(f / 128.0F, (f1 + 7.99F) / 128.0F);
        GL11.glVertex3f(this.posX - f2, this.posY + 7.99F, 0.0F);
        GL11.glTexCoord2f((f + f3 - 1.0F) / 128.0F, f1 / 128.0F);
        GL11.glVertex3f(this.posX + f3 - 1.0F + f2, this.posY, 0.0F);
        GL11.glTexCoord2f((f + f3 - 1.0F) / 128.0F, (f1 + 7.99F) / 128.0F);
        GL11.glVertex3f(this.posX + f3 - 1.0F - f2, this.posY + 7.99F, 0.0F);

 

As you can see there is 0.0F as the z coordinate, so the zLevel variable has no effect.

Instead, you have to use GL11.glTranslate(0.0F, 0.0F, zLevel);

 

Now it works.
