Hey, All! I was looking into the help file at all the drawing utilities and I was wondering if you draw a translucent line that follows your cursor. Upon looking for ideas I came across this thread (1.0) and saw UEZ's response. I also came across another post that UEZ replied to and found this reply (1.1) where he shows how you can draw on the desktop. This is what I'm looking for however I'd still like to be able to interact with a designated application and have the line/curve/vector passively follow it. Obviously we don't move our cursor very linearly so it would have to be able to draw on vectors. Am I over complicating this? Any ideas or starting points I should look more into? 1.0 #include <GUIConstantsEx.au3> #include <WindowsConstants.au3> Global Const $aFullScreen = WinGetPos(WinGetHandle("[TITLE:Program Manager;CLASS:Progman]")) Global $iHeight = 4 Global Const $hGUI = GUICreate("Screen Ruler Underline for free :-)", $aFullScreen[2], $iHeight, $aFullScreen[0], MouseGetPos(1), $WS_POPUP, BitOR($WS_EX_TOPMOST, $WS_EX_TRANSPARENT)) GUISetBkColor(0x000000) WinSetTrans($hGUI, "", 0xA0) GUISetState() HotKeySet("{ESC}", "_Exit") Do WinMove($hGUI, "", $aFullScreen[0], MouseGetPos(1)) Until Not Sleep(50) Func _Exit() GUIDelete() Exit EndFunc _____________ 1.1 #include <GUIConstantsEx.au3> #include <WindowsConstants.au3> #include <WinAPI.au3> AutoItSetOption("GUIOnEventMode", 1) Global $hGUI, $hDC, $hPen, $obj_orig $hGUI = GUICreate("", @DesktopWidth, @DesktopHeight, 0, 0, $WS_POPUP) WinSetTrans($hGUI, "", 1) GUISetState() _line() Func _line() $hDC = _WinAPI_GetWindowDC(0) ; DC of entire screen (desktop) $hPen = _WinAPI_CreatePen($PS_SOLID, 2, 0x00ff) $obj_orig = _WinAPI_SelectObject($hDC, $hPen) GUISetOnEvent($GUI_EVENT_PRIMARYDOWN, "Draw", $hGUI) GUISetOnEvent(-3, "_Exit") Do Until Not Sleep(1000) EndFunc ;==>_line Func Draw() Local $aMC, $mxo, $myo $aMC = GUIGetCursorInfo($hGUI) Do GUISetCursor(0, 1, 0) $mxo = $aMC[0] $myo = $aMC[1] $aMC = GUIGetCursorInfo($hGUI) If $mxo <> $aMC[0] Or $myo <> $aMC[1] Then _WinAPI_DrawLine($hDC, $aMC[0], $aMC[1], $mxo, $myo) _WinAPI_RedrawWindow(_WinAPI_GetDesktopWindow(), 0, 0, $RDW_INVALIDATE) $mxo = $aMC[0] $myo = $aMC[1] EndIf Sleep(10) Until Not $aMC[2] EndFunc Func _Exit() _WinAPI_SelectObject($hDC, $obj_orig) _WinAPI_DeleteObject($hPen) _WinAPI_ReleaseDC(0, $hDC) Exit EndFunc

Hi! I'm trying to script an ellipse drawing algorithm in AutoIT for learning purposes. I use an edit control to "draw" the ellipse with characters. The code i have works kinda good but i would like to see if others around here know a better algorithm to do it.. I would like to be able to give the x, y and width, height arguments to the function and not have to start at the middle point and draw the ellipse around it. side note, the ellipse glitches when it has to be 2 pixels high too.. func ellipsePlotPoints ($xc,$yc, $x,$y) pixel ($xc + $x, $yc + $y) pixel ($xc - $x, $yc + $y) pixel ($xc + $x, $yc - $y) pixel ($xc - $x, $yc - $y) endfunc func ellipse($xc,$yc, $a,$b) local $a2 = $a * $a local $b2 = $b * $b local $twoa2 = 2 * $a2 local $twob2 = 2 * $b2 local $p local $x = 0 local $y = $b local $px = 0 local $py = $twoa2 * $y ; Plot the initial point in each quadrant. ellipsePlotPoints ($xc,$yc, $x,$y) ; Region 1 $p = int($b2 - ($a2 * $b) + (0.25 * $a2)) while ($px < $py) $x+=1 $px += $twob2 if ($p < 0) then $p += $b2 + $px else $y-=1 $py -= $twoa2 $p += $b2 + $px - $py endif ellipsePlotPoints ($xc,$yc, $x,$y) wend ; Region 2 $p = int ($b2 * ($x+0.5) * ($x+0.5) + $a2 * ($y-1) * ($y-1) - $a2 * $b2) while ($y > 0) $y-=1 $py -= $twoa2 if ($p > 0) then $p += $a2 - $py else $x+=1 $px += $twob2 $p += $a2 - $py + $px endif ellipsePlotPoints ($xc,$yc, $x,$y) wend endfunc

Greetings! I am having an issue that I can't seem to be able to figure out. I would really appreciate an extra pair of eyes to validate my work so far. All this is, so far, is just a bunch of shapes on an HTML page. It is to be a very simple game ( just exploring Javascript through making this ) but right now I am just building the framework/elements. The script is this <!DOCTYPE HTML> <html> <head> <style> body { margin: 0px; padding: 0px; } #canvas-container { width: 100%; text-align:center; } canvas { display: inline; } </style> </head> <body onload="startUp()"> <div id="canvas-container"> <canvas id="game" width="300" height="500"></canvas> </div> <script> var canvas = document.getElementById('game'); var ctx = canvas.getContext('2d'); var x = canvas.width; var y = canvas.height; var scoreVal = 0; var itemXRand = Math.floor(Math.random() * x) + 1 ctx.stroke(); function cloud(){ ctx.beginPath(); ctx.moveTo(170, 30); ctx.bezierCurveTo(130, 100, 130, 150, 230, 150); ctx.bezierCurveTo(250, 180, 320, 180, 340, 150); ctx.bezierCurveTo(420, 150, 420, 120, 390, 100); ctx.bezierCurveTo(430, 40, 370, 30, 340, 50); ctx.bezierCurveTo(320, 5, 250, 20, 250, 50); ctx.bezierCurveTo(200, 5, 150, 20, 170, 80); ctx.closePath(); ctx.lineWidth = 5; ctx.fillStyle = '#8ED6FF'; ctx.fill(); ctx.strokeStyle = '#0000ff'; ctx.stroke(); } function workArea(){ ctx.beginPath(); ctx.rect(0, 0, x, y); ctx.fillStyle = "#2ab9ff"; ctx.fill(); ctx.stroke = 1; } function topRect(){ ctx.beginPath(); ctx.rect(0, 0, x, 30); ctx.fillStyle = "#D3D3D3"; ctx.fill(); ctx.stroke = 1; } function scoreKeep(){ ctx.font = "15px Arial"; ctx.fillStyle = "#000000"; ctx.fillText("Score "+scoreVal,5, 25); } function bttmRect(){ ctx.beginPath(); ctx.rect(0, y-30, x, 30); ctx.fillStyle = '#5bc928'; ctx.fill(); ctx.stroke = 1; } function monstRect(){ ctx.beginPath(); ctx.rect(0, y-80, x, 30); ctx.fillStyle = 'red'; ctx.fill(); ctx.stroke = 1; } function itemCirc(){ var centerX = itemXRand var radius = 15; var positionY = 45; ctx.beginPath(); ctx.arc(centerX, positionY, radius, 0, 2 * Math.PI, false); ctx.fillStyle = randomColor(); ctx.fill(); ctx.lineWidth = 1; ctx.strokeStyle = '#003300'; ctx.stroke(); } function startUp(){ workArea(); topRect(); bttmRect(); scoreKeep(); itemCirc(); monstRect(); cloud(); } function randomColor(){ return('#'+Math.floor(Math.random()*16777215).toString(16)); } </script> </body> </html> The issue is that cloud() and monstRect() will not show up when the page loads. If I comment out workArea(), topRect(), and bttmRect() in the function "startUp()" then monstRect() and cloud() show up. I've re-read those little snippets of code for those three areas that I comment out and I can't see where I have gone wrong. Any advice or if you can spot my mistake I would really appreciate it. Thank you! -Reiz
