Debugging Tips

Issue: My game only shows a white screen

• Did you remember to call game.start()?

Issue: My Actor or Entity is not drawing on the screen:

• Ensure your Actor or Entity is added to the correct Scene.
• Add a name to your Actor or Entity and toggle debug to see if you can see it's name in debug
• Is your Actor or Entity offscreen? Check it's position in the debugger

Issue: Poor/laggy game performance

• Consult our performance guide

Issue: My images show up as black rectangles on mobile or other platforms

• Ensure your images are less than 4k pixels in width or height, this is usually the limit for mobile devices in webgl.
