What I'm trying to do, is that on the press of a key, in this case, Z an overlay appears if you're holding an item. I know everything up until the rendering works. However, when it tries to render, my method for finding the xPos and yPos to start drawing my Rectangle gets screwed up, and goes into negatives, and even when it's not in negatives, it won't render.

 

Here's my code for KeyInputHandler: http://pastebin.com/JNNVSnDu

Here's what the numbers are coming up as:

Scaled Width: 427

Scaled Height: 240

X-Pos 299

Y-Pos 112

 

And it doesn't render. Any help would be greatly appreciated! Thanks in Advance

Big mistake: (accssing) Proper way:

int w = event.resolution.getScaledWidth();
int h = event.resolution.getScaledHeight();

 

And again - you are doing it wrong. Rendering ANYTHING onto overlay SHOULD happen in GuiRenderGameOverlayEvent.

After you have you KeyBinding object , you can chk for it's "isPressed" or something like it. Then you can use this variable inside GRGOEvent. Inside that event (overlay), you call code I gave you above.

Thanks! It's working perfectly now!
