I'm trying to write a code to change the image of a button.... I want something that if i hit that button it's change it's graphics.....and when i hit that another time it's return to his original image and so on,to simulate a simple "button on","button off" that change if i give him thw input to. Here's a part of the wrong code: if mousedown(1) and mx>711 and mx<790 and my>0 and my<17 setscroll=setscroll_on ;swap of the image if i held down the mouse button endif |

Const SetScroll_On = 1 Const SetScroll_Off = 0 If MouseDown(1) If MX>711 and MX<790 and MY>0 and MY<17 If SetScroll = SetScroll_On SetScroll = SetScroll_Off Else SetScroll = SetScroll_On Endif Endif While MouseDown(1) Wend Endif |

Urgh i didn't think that's so easy the resolution... I have tried all but not the most obvious thing -_-' Many thanks! |

If SetScroll can only be either True or False (1 or 0), you can simplify the code a little:If MouseDown(1) If MX>711 and MX<790 and MY>0 and MY<17 SetScroll = 1 - SetScroll ; This will toggle SetScroll between 0 and 1 Endif While MouseDown(1) Wend Endif |

or you could gosetscroll = not setscroll which also toggles its value from 0 to 1 etc. |

With the original code, though - more than the two states are possible. Allowing for a choice of any number of settings for the button: ie. Setscroll 0 ......... OFF Setscroll 1 ......... ON Setscroll 2 ......... AUTO Setscroll 3 ......... ADVANCED (or whatever, depending on button uses) |
