Thread: Need help making an image move from one side of screen to the other.

Hi, I am doing a college project and have been told I have to create a splash screen with an image that moves across the screen I have tried and tried but always end up with errors or failing.....SpaceShip.png is the image I need animating....

Attached below is a copy
I had to make the buttons separate classes as the project requirements said so....

Here is my code:

You say you have errors. What are they? What do you mean when you say that it fails? If you want help, you'll have to provide an SSCCE that demonstrates the problem.
