Socoder -> Blitz -> Making Block?
Mon, 10 Sep 2007, 12:18
Hotshot	Hiya there, What I am trying to do is making some block by using the mouse Put whatever block positions or size of the block. for example If I made small block then I move them in the middle and if I make another block then I put it somewhere(like right or left or top or bottom). But at the moment...I only got one block....how do you make muti blocks? Graphics (640,480,16,2) SetBuffer BackBuffer() Dim x(100) Dim y(100) Dim Target_X(100) Dim Target_y(100) While Not KeyDown(1) Cls If MouseHit(1) i=i+1 Color 255,0,0 X(i)=MouseX() Y(i)=MouseY() Target_X(i)=MouseX() Target_y(i)=MouseY() EndIf Color 255,0,0 Rect X(i),Y(i),Target_X(i),Target_Y(i) Color 255,255,0 Text X(i),Y(i),"Block "+i Flip Wend --v

JL235	First I don't know what you mean. This is kinda a guess, but I'd like to ask you to explain again or further. Maybe draw an example of what you want to achieve. Second, i will eventually increment greater then the size of the array and you'll (hopefully) get an array index out of bounds (although I'm finding here it's only caught in the debugger which is a HUGE flaw). So you should check if the size is valid (but arrays can't store their size so it's up to you to do this code). Third, is something like this what your after? Graphics (640,480,16,2) SetBuffer BackBuffer() Const SIZE = 100 Dim X(SIZE) Dim Y(SIZE) Dim Target_X(SIZE) Dim Target_y(SIZE) Local count = 0 While Not KeyDown(1) Cls If MouseHit(1) count = count+1 Local i = count Mod SIZE Color 255,0,0 X(200)=MouseX() Y(i)=MouseY() Target_X(i)=MouseX() Target_y(i)=MouseY() EndIf For j = 0 To SIZE If Not (x(j) = 0 And y(j) = 0 And Target_X(j) = 0 And Target_Y(j) = 0) Color 255 - (j8 Mod 255), j5 Mod 255, 0 Rect X(j),Y(j),Target_X(j),Target_Y(j) Color 0, 0, 0 Rect X(j),Y(j),Target_X(j),Target_Y(j), False Color 255, 255, 0 Text X(j),Y(j),"Block "+j EndIf Next Flip Wend --v

JL235	Or do you mean something like: Graphics (640,480,16,2) SetBuffer BackBuffer() Type Rectangle Field x Field y Field width Field height End Type Local lastRectangle.Rectangle = Null While Not KeyDown(1) Cls If MouseHit(1) If lastRectangle = Null lastRectangle = newRectangle(MouseX(), MouseY()) ElseIf isValidRectangle(lastRectangle) lastRectangle = newRectangle(MouseX(), MouseY()) Else setRectangleWidth(lastRectangle, MouseX(), MouseY()) EndIf EndIf For r.Rectangle = Each Rectangle drawRectangle(r) Next Flip Wend ; Determins if a Rectangle is valid or not. ; A valid Rectangle is one with a width and height ; which is not equal to 0. ; Return true if it is valid, false if not. Function isValidRectangle(r.Rectangle) Return Not (r\width = 0 And r\height = 0) End Function Function newRectangle.Rectangle(x, y) Local r.Rectangle = New Rectangle r\x = x r\y = y r\width = 0 r\height = 0 Return r End Function Function setRectangleWidth(r.Rectangle, x, y) r\width = x-r\x r\height = y-r\y End Function Function drawRectangle(r.Rectangle) If isValidRectangle(r) ;draw inside Color 200, 0, 0 Rect r\x, r\y, r\width, r\height ;draw outline Color 0, 0, 0 Rect r\x, r\y, r\width, r\height, False EndIf End Function --v Also I didn't realise until I wrote the above code. Blitz doesn't do short-circuiting. If you changed the if statement above to: If lastRectangle = Null Or isValidRectangle(lastRectangle) lastRectangle = newRectangle(MouseX(), MouseY()) Else setRectangleWidth(lastRectangle, MouseX(), MouseY()) EndIf --v It no longer works because it runs the 'isValidRectangle' function if it's null, which it shouldn't. I cannot think of another language which doesn't allow short-circuiting.

Hotshot	Second one is very good but I try change the colors so I can see line when I drag the mouse down (when become square)....do u know what i mean? Like in Blitz 3D they have curors flashing as u know where is. When I move the mouse then when I want to click the mouse the square line is ready then I want drag it and it should show flashing rect then once I am happy it then I let my mouse button off then I go create another square or rectangle one...

Forklift_Fred	You can use free image hosts like https://ImageShack.us or https://PaintedOver.com to post your pic here. ImageShack is widely used but can be slow. Both will give you a thumbnail and code to paste here. With ImageShack it is the second code, with PaintedOver it's the first. Wherever you host it, you'll need the code with [img]... rather than [img=...] Here's a random demonstration: [url=https://paintedover.com/uploads/show.php?loc=0735&f=33t_445.jpg][img]https://img0735.paintedover.com/uploads/thumbs/0735/33t_445.jpg[/img][/url] --v gives the following result: Not sure how to do the flashing rectangle in 3D though. -=-=- Come rain or shine...

Hotshot	img208.imageshack.us/my.php?image=blockun3.png the flashing rect(on when I am draging the mouse on what size I want then once I am happy with it then I let the mouse button off) then create it. Hope that should explain
