(I must admit though, I have spent all of 5 mins trying to solve it!) ha ha In WM_TIMER, keypresses are checked every timer loop which is great for scrolling games and moving sprite games, but I have another application in mind. My app scans for keypresses in WM_TIMER (as in the GAMEAPI examples) when I press any of the direction keys, my position counter zooms up or down etc. I want to be able to do the following; Press an arrow key Increment by 1 Press the same arrow key Increment by 1 Get my drift? What I get is Press an arrow key Increment until I release the arrow key (my counter zooms up and up!) AAARRRGGGHHH! I must have missed something, but I have tried all the examples and the help and still cant find anything to help me! I have even tried the following; WM_KEYDOWN: if (KeysPressed$[wParam$] = 1) KeysPressed$[wParam$] = 0; else KeysPressed$[wParam$] = 1; end; But that does not work. Not massively urgent or important - Im sure if I scratch my head enough I will find it. Cheers Mike. Editor of \'Voice of the PPL\' the newsletter for the PPL by the PPL!

In the WM_Timer section change: if (KeysPressed$[keys.vkLeft$] and FirstTime$) ... FirstTime$=false; end; and in MAINPROC's WM_KEYUP set it back to true There is a crack, a crack in everything. That's how the light gets in. (L. Cohen) | ||

  Registered Member #49 Joined: Sun Sep 17 2006, 03:02pmPosts: 1129 | Question: rather than even checking in the WM_TIMER event, why not just increment your counter in the WM_KEYDOWN event? Then you don't even need the FirstTime$ variable or all the extra associated logic. Or am I missing something here? Eric Pankoke Founder Point Of Light Software http://www.polsoftware.com/ | ||

I was under the impression that the key checks in WM_TIMER could not be used in the WM_KEYDOWN section. (Dont ask me why I thought that! rofl) Any hoo, have a working piece of code so my quest has ended! Editor of \'Voice of the PPL\' the newsletter for the PPL by the PPL!
