DrawImage BeginPic, 700, 0 DrawImage TitleText, 700, 0 FreeImage BeginPic FreeImage TitleText ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; While Not KeyHit(1) ; now we can place the game tiles on screen Flip Wend End ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; Thanks for helping. |

Welcome Pat33 Normally you would use the Cls command to clear the whole screen, you can't really remove single images from the screen. Inside your main loop you should do something like this: While Not KeyHit(1) Cls ; draw all your stuff here Flip Wend Hope this helps ;) |

Pat33- To expand a little on VIP3R's answer to your question, CLS is the "Clear Screen" command. When you're done with your setup screen and title, just add a CLS command BEFORE you start drawing the game screens, and all the former images will be erased. What VIP3R was referring to in the code above is what's called the "Game Loop", where all the action of the game takes place. Generally when you want to remove something from the screen, like an enemy spaceship that's been blown up, all you do is clear the screen with a CLS command then redraw everything else, but omit the enemy spaceship. This redrawing happens every "frame" (usually 60 times a second or so), so it's very fast. |
