Jayenkai	Created : 07 May 2007 Language : Blitz Redefinable Controls Quick and easy redefinable key functions.
First off, here's the 2 functions. Function hitbutton(button,sensitive#=0.5) out=0 If button>0 And button<256 If KeyDown(button) Then out=1 EndIf For port=0 To 3 If button>299+(port50) And button<340+(port50) If button=300+(port50) And JoyX(port)<-sensitive# Then out=1 If button=301+(port50) And JoyX(port)>sensitive# Then out=1 If button=302+(port50) And JoyY(port)<-sensitive# Then out=1 If button=303+(port50) And JoyY(port)>sensitive# Then out=1 If button=304+(port50) And JoyZ(port)<-sensitive# Then out=1 If button=305+(port50) And JoyZ(port)>sensitive# Then out=1 If button=306+(port50) And JoyU(port)<-sensitive# Then out=1 If button=307+(port50) And JoyU(port)>sensitive# Then out=1 If button=308+(port50) And JoyV(port)<-sensitive# Then out=1 If button=309+(port50) And JoyV(port)>sensitive# Then out=1 If button=310+(port50) And (JoyHat(port)=270 Or JoyHat(port)=315 Or JoyHat(port)=225) Then out=1 If button=311+(port50) And (JoyHat(port)=90 Or JoyHat(port)=45 Or JoyHat(port)=135) Then out=1 If button=312+(port50) And (JoyHat(port)=0 Or JoyHat(port)=315 Or JoyHat(port)=45) Then out=1 If button=313+(port50) And (JoyHat(port)=180 Or JoyHat(port)=225 Or JoyHat(port)=135) Then out=1 If button>320+(port50) And button<340+(port50) And JoyDown(button-(320+(port50)),port) Then out=1 EndIf Next Return out End Function Function Findbutton(sensitive#=0.5,AllowPorts=1,WithZUV=0) ; sensitivity for analogue joys ; Allow Ports = Joyports to allow (+1) so 1 checks port 0, 2 checks 1, 3 for 2 and 4 checks 3! Got that!! Good! ; and only allow WithZUV if you're sure the user's joystick's Z, U and V are working right! out=0 For keychk=1 To 255 If KeyDown(keychk) Then out=keychk Next For port=0 To AllowPorts-1 If JoyX(port)<-sensitive# Then out=300+(port50) If JoyX(port)>sensitive# Then out=301+(port50) If JoyY(port)<-sensitive# Then out=302+(port50) If JoyY(port)>sensitive# Then out=303+(port50) If WithZUV=1 If JoyZ(port)<-sensitive# Then out=304+(port50) If JoyZ(port)>sensitive# Then out=305+(port50) If JoyU(port)<-sensitive# Then out=306+(port50) If JoyU(port)>sensitive# Then out=307+(port50) If JoyV(port)<-sensitive# Then out=308+(port50) If JoyV(port)>sensitive# Then out=309+(port50) EndIf If JoyHat(port)=270 Then out=310+(port50) If JoyHat(port)=90 Then out=311+(port50) If JoyHat(port)=0 Then out=312+(port50) If JoyHat(port)=180 Then out=313+(port50) For button=320 To 340 If JoyDown(button-(320+(port50)),port) Then out=button Next Next Return out End Function --v Use FindButton(), which goes through all keys, and then Joypad controls, checking to see what's pushed. Record the outputted value, then check it with HitButton(value) A short example.. Graphics 640,480,0,2 ; - Gives us full size window Dim Key(10,5) ; - Holds 10 keys for 5 users. Can't imagine more than that fitting on a PC ;) SetBuffer BackBuffer() Const K_Up=1 Const K_Down=2 Const K_Left=3 Const K_Right=4 Const K_Fire=5 ; First, Get 5 redefinable keys for player 1 For n=1 To 5 Repeat Select n Case K_Up txt$="Up" Case K_Down txt$="Down" Case K_Left txt$="Left" Case K_Right txt$="Right" Case K_Fire txt$="Fire" End Select Cls Text 320,240,"Hit Key for "+txt$,1,1 Flip Keyed=FindButton() DebugLog keyed Until Keyed<>0 Key(n,1)=Keyed ;Once a button has been hit, we have to wait until all buttons are un-hit Repeat Until FindButton()=0 Next ; Then do a simple display Repeat Cls If HitButton(Key(K_Up,1)) Then Text 320,20,"UP",1,1 If HitButton(Key(K_Down,1)) Then Text 320,460,"DOWN",1,1 If HitButton(Key(K_Left,1)) Then Text 40,240,"LEFT",1,1 If HitButton(Key(K_Right,1)) Then Text 600,240,"RIGHT",1,1 If HitButton(Key(K_Fire,1)) Then Text 320,240,"FIRE",1,1 Flip Until KeyDown(1) End ;---- Don't forget to include the 2 functions at the bottom ;) ---- --v

Paul	err... this just locks up :S Adding a delay in the For keychk=1 To 255 If KeyDown(keychk) Then out=keychk Delay 1;<-- Next allows me to close the program with the ex instead of taskmanager. Dont know if it's got anything to do with my wacky joystick?

Jayenkai	Yeah, could be a wacky joystick.. Probably best to disable joystick support until the player enables it.

Paul	anyway, here's a function to get the name of the key pressed Needs user32.decels GetKeyNameText% (lParam%,lpBuffer*,nSize%):"GetKeyNameTextA" My decels file didn't have the star after the lpBuffer so it didn't work at first. While Not KeyHit(1) For i=2 To 255 If KeyHit(i) Then Print getkeyname$(i) Next Delay 50 Wend End Function BankToStirng$(B,offset=1) DebugLog BankSize(B) For i = offset To BankSize(B) ok = PeekByte(B,i-1) If ok = 0 Then Exit d$ = d$ + Chr$(ok) Next Return d$ End Function Function getkeyname$(key%,bank=0) If bank=0 Then bank=CreateBank(256) api_GetKeyNameText(key% Shl 16 Or 1 Shl 25,bank,256) tmp$=BankToStirng$(bank) FreeBank(bank) If tmp$<>"" Then Return tmp$ Select key% Case 210:Return "INSERT" Case 199:Return "HOME" Case 201:Return "PAGE UP" Case 211:Return "DELETE" Case 207:Return "END" Case 209:Return "PAGE DOWN" Case 69 :Return "NUM LOCK" Case 156:Return "ENTER" Case 157:Return "CTRL" Case 219:Return "WINDOWS" Case 220:Return "WINDOWS" Case 208:Return "Down" Case 200:Return "UP" Case 203:Return "LEFT" Case 205:Return "RIGHT" Case 197:Return "NUM LOCK" End Select Return "" End Function --v
