Blitz Challenge (Great for learning)

[Azan]

Ok this is for all those people who are new to blitz, this is so that you may tackle a real challenge and see if you have trouble with it, if you do thats great because then you can get help and learn from your mistakes, its the best way to learn blitz.

Ok heres what you need to make, just a simple program where a 2d circle follows the mouse pointer, this doesnt require types or anything so its fairly simple.

Hints:
Use MouseX() and MouseY() to get the coordinates of your pointer, use < and > signs to do direction checks.

When you are done post it here.

i assume im not allowed to participate?
;D

Nope new people only

ok hows this?

Graphics 640,480

SetBuffer BackBuffer()

Repeat
Cls

Text 320,0,"Click to reset mouse",True

Text 0,0,"Mouse X:"+MouseX()
Text 0,10,"Mouse Y:"+MouseY()

If MouseDown(1) Or MouseDown(2) Then MoveMouse 320,240

Text MouseX(),MouseY(),"O",True,True

Flip

Until KeyHit(1)

End

Excellent, however you dont need the reset mouse part (but hey its an addon thats good).

You got the challenge almost right, but a circle has to follow the mouse. But its close enough, heres your same program only with the circle following the mouse

Graphics 640,480

SetBuffer BackBuffer()
x=50
y=50
Repeat
Cls

Text 320,0,"Click to reset mouse",True

Text 0,0,"Mouse X:"+MouseX()
Text 0,10,"Mouse Y:"+MouseY()

If MouseDown(1) Or MouseDown(2) Then MoveMouse 320,240

Text x,y,"O"
If x<MouseX() Then
	x=x+1
EndIf
If x>MouseX() Then
	x=x-1
EndIf
If y<MouseY() Then
	y=y+1
EndIf
If y>MouseY() Then
	y=y-1
EndIf

Flip

Until KeyHit(1)

End

umm, why not just replace

Text x,y,"O"

with

Text MouseX(),MouseY(),"O"

and then that makes the whole program a LOT simpler

[Azan]

B/C it was supposed to follow the mouse, not be at the mouses coordinates, as said above. SpikeSpiegel did it the mousex(),mousey() way which is good, but it wasnt exact to the challenge.

[Umbrafire]

OHHH....that makes more sense lol

[Azan]

BTW Jiub, you can set the blitz challenges, lets say once per week or something?

[Umbrafire]

sure, i'll try to do it soon, I cant guarantee anything though

[Azan]

Meh its not like anyone will actualy attempt it. (we need more programmers to post here, and that means you too Lobstrosity
