Teasy	Created : 21 August 2007 Language : Blitz Interface re-handler Encapsulates Blitz' native input routines for keyboard, mouse and joystick, enabling multi-point input polling.
This system allows you to poll keys and buttons on multiple points in a program, without the need to store it in a variable, as the system does this for you when you call the UpdateInput function. The only difference is that you can use KeyHit[ Key_Esc ] using square brackets rather than braces. List of available arrays and functions: - Main System Global KeyDown[ 255 ] Global KeyHit [ 255 ] Global MouseDown[ 255 ] Global MouseHit [ 255 ] Global JoyDown[ 255 ] Global JoyHit [ 255 ] Global ShiftDown,ControlDown,AltDown Global ShiftHit ,ControlHit ,AltHit Global CtrlDown Function UpdateInput() - Single-point input poll functions Function MouseUp( Button ) Function JoyUp( Button ) Function KeyUp( Key ) - Library test function Function TestInputs() - Other Functions Function waitkeyordelay( time=0 ) Function AnyKeyDown% () Function AnyKeyHit% () Function FlushInput( AutoOnly = False ) ;------------------------------------------------------------------------------- ; * Interface re-handler (mouse, keyboard, joystick) ; Version 2007 Mar 04 Rev 02 ;------------------------------------------------------------------------------- ; Encapsulation enables multi-point input polling ; These can be accessed directly (after using UpdateInput each frame) Global KeyDown[ 255 ] Global KeyHit [ 255 ] Global MouseDown[ 255 ] Global MouseHit [ 255 ] Global JoyDown[ 255 ] Global JoyHit [ 255 ] Global ShiftDown,ControlDown,AltDown Global ShiftHit ,ControlHit ,AltHit Global CtrlDown ; These are not to be accessed directly Global KeyWasDown [ 255 ] Global MouseWasDown[ 255 ] Global JoyWasDown [ 255 ] Function UpdateInput() For Index = 0 To 255 KeyDown[ Index ] = KeyDown( Index ) KeyHit [ Index ] = KeyHit ( Index ) MouseDown[ Index ] = MouseDown( Index ) MouseHit [ Index ] = MouseHit ( Index ) JoyDown[ Index ] = JoyDown( Index ) JoyHit [ Index ] = JoyHit ( Index ) Next ControlDown = KeyDown[ Key_LeftControl ] Or KeyDown[ Key_RightControl ] ShiftDown = KeyDown[ Key_LeftShift ] Or KeyDown[ Key_RightShift ] AltDown = KeyDown[ Key_LeftAlt ] Or KeyDown[ Key_RightAlt ] ControlHit = KeyHit[ Key_LeftControl ] Or KeyHit[ Key_RightControl ] ShiftHit = KeyHit[ Key_LeftShift ] Or KeyHit[ Key_RightShift ] AltHit = KeyHit[ Key_LeftAlt ] Or KeyHit[ Key_RightAlt ] CtrlDown = ControlDown End Function ; Note: Single-point input poll function Function MouseUp( Button ) If MouseDown[ Button ] MouseWasDown[ Button ] = MouseDown[ Button ] Return False Else If MouseWasDown[ Button ] <> MouseDown[ Button ] MouseWasDown[ Button ] = MouseDown[ Button ] Return True Else Return False EndIf EndIf End Function ; Note: Single-point input poll function Function JoyUp( Button ) If JoyDown[ Button ] JoyWasDown[ Button ] = JoyDown[ Button ] Return False Else If JoyWasDown[ Button ] <> JoyDown[ Button ] JoyWasDown[ Button ] = JoyDown[ Button ] Return True Else Return False EndIf EndIf End Function ; Note: Single-point input poll function Function KeyUp( Key ) If KeyDown[ Key ] KeyWasDown[ Key ] = KeyDown[ Key ] Return False Else If KeyWasDown[ Key ] <> KeyDown[ Key ] KeyWasDown[ Key ] = KeyDown[ Key ] Return True Else Return False EndIf EndIf End Function ; Library test function Function TestInputs() Local Input Graphics 200,400 , 0,2 Repeat UpdateInput For Input = 0 To 255 If MouseHit [ Input ] Then Print "Mouse HIT"+Input If MouseDown[ Input ] Then Print "Mouse DOWN"+Input If MouseUp ( Input ) Then Print "Mouse UP"+Input If KeyHit [ Input ] Then Print "Key HIT"+Input If KeyDown[ Input ] Then Print "Key DOWN"+Input If KeyUp ( Input ) Then Print "Key UP"+Input If JoyHit [ Input ] Then Print "Joy HIT"+Input If JoyDown[ Input ] Then Print "Joy DOWN"+Input If JoyUp ( Input ) Then Print "Joy UP"+Input Next VWait Delay 10 Until KeyHit[1] End Function ;-- Other Functions ------------------------------------------------------------ Function waitkeyordelay( time=0 ) start=MilliSecs() Repeat For key=0 To 255 If KeyHit( key ) Then esc=True:Exit Next For button=0 To 3 If MouseHit( button ) Then esc=True:Exit Next For joy=0 To 255 If JoyHit( joy ) Then esc=True:Exit Next If time>0 If MilliSecs()-start>=time esc=True EndIf EndIf Until esc FlushKeys FlushMouse FlushJoy End Function Function AnyKeyDown% () For Counter = 1 To 255 If KeyDown ( Counter ) > 0 AnyKey = Counter Exit EndIf Next FlushKeys () Return AnyKey End Function Function AnyKeyHit% () For Counter = 1 To 255 If KeyHit ( Counter ) > 0 AnyKey = Counter Exit EndIf Next FlushKeys () Return AnyKey End Function ; reset all input device poll values (keyboard, mouse, joystick) ; both auto and manual by default Function FlushInput( AutoOnly = False ) Local Input If Not AutoOnly For Input = 0 To 255 KeyHit Input ;KeyDown Input MouseHit Input ;MouseDown Input JoyHit Input ;JoyDown Input Next EndIf FlushKeys FlushMouse FlushJoy End Function --v
