there's a bunch of commands to pause execution (pause) until a key,mouse button is pressed, or timer =n, how would i go about pausing until a SPECIFIC button is pressed, or a SPECIFIC variable = something? |

Repeat Delay 5 until somthing=somthing? Edit: heres a example, use the Up arrow to toggle pause on and off Graphics 500,300,16,2 SetBuffer BackBuffer() x=50 y=50 While Not KeyHit(1) Cls Rect x,y,15,15,2 x=x+1 If x>480 x=0 If KeyHit(200) pause=2 End If While pause=2 If KeyHit(200) pause=1 End If If KeyHit(1) End End If Delay 5 Wend Delay 5 Flip Wend End |

How About:Const mykey= ;scancode for key ;do stuff ;here comes the pause While Not KeyDown(mykey) Wend ;more stuff after the pause |

This. While Not KeyDown(mykey) Wend May crash in rare cases, when high priority background tasks can't breath, therefor always add a delay 1: While Not KeyDown(mykey) delay 1 Wend IT may not crash on most machines, but basicly it's bad style anyway since it will eat 100% of the CPU resources. The crash only happened after several minutes of inactvity (so the loop was executed for several minutes), an empty loop may be used in other situations noless, eg: While Not KeyDown(mykey) ; wait for key, may take minutes or even hours delay 1 Wend While KeyDown(mykey) ; wait for key release will take only seconds Wend |
