How do I troubleshoot black screen?

Hello all,

I'm having trouble with something that I assume is very basic. I've searched the forums but can't quite find what I'm looking for. My first game has just couple of events. When I preview, rather than showing the assets on the layout, I just get a black screen. I must be doing something wrong with the basic setup of my sprites.

Thanks for any help you can provide, and please let me know if additional details are needed.

You have a while loop in the second event that runs infinitely. That is why the C3 runtime never will render the first frame, so you get a black screen.

Since you don't have any other condition, it basically reads:

While () : Do stuff.

I guess your intent was to only add 0.1 to pump while E is pressed.

In that case try the following:

Keyboard: Key E is down: Add 0.1 to Pump

This will at 0.1 to Pump every tick while E is pressed, basically meaning 6.0 per second (since the engine runs at 60 frames per second).

If you need smaller amounts, either use a smaller value, or add another condition like every 0.1 seconds.

Hey thanks for the quick reply! That did it. Appreciate the workaround to accomplishing something similar, as well.

Cheers
