Which event do I need to handle rendering with Tooltips? Its for something a little similar to Thaumcraft's Aspect display above the tooltip.

ItemTooltipEvent? Gives you (last) chance to modify rendering.

ItemTooltipEvent? Gives you (last) chance to modify rendering.

 

That allows me to add to a tooltip (I am using that event) but it does not allow me to render additional information - such as what Thaumcraft does with its aspects.

I found a workaround, in the event that I cannot find a proper method: I used

GuiScreenEvent#DrawScreenEvent

and recreated

GuiUtils#drawHoveringText

, removing all the rendering code (this gets me the X and Y of the tooltip, as well as its size). Its a bit messy, but it works for my purposes.

Okay, I forgot - it's not designed to help (event).

 

You can: (in event)

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

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

 

Then using that you can render (image i guess, or really anything) using one of Gui.class methods (or other ones).

 

Big note: image will try to render in zLevel = 0, which is not desired since it will just not work (in that event).

At least, that is what I remember from some past problems (maybe changed).

 

In that case you can use: GL11.glTranslate(0.0F, 0.0F, zLevel);
