Moving a Box with the Mouse

BlitzPlus Forums/BlitzPlus Beginners Area/Moving a Box with the Mouse

Apollonius(Posted 1+ years ago) #1
Ok, how would I make it so, where ever you click on the "Title" image, and left click is down. And you move your mouse and the box moves with it.

So I'm thinking, you'd need to know your MouseX and MouseY, then make something analyse, if your mosue is on the image. Then check if your left click is down. Then compare your MouseX and MouseY with your box_x and box_y. So like if your mouse moves while doing the two things it notes a +number or -number and applies it to the box_x and box_y.
Well thats just my theorie tho lol..

But how would i do that?
Thanks for the help.

Do you wonder why with an explanation like that?

Start at the beginiing Kaisuo and explain things slowly and accurately. You never know, someone might actually understand what you are saying and MAYBE they will provide a solution - stranger things have happened!

Perhaps this is of some help to you.

Copy, Pasted and tested that code. This is what I wanted somewhat.

Could anyone explain abit this to me in detail. This gonna help my learning of Blitz

Alot of symbol :|
If MH And MX => b\x# And MX < (b\x#+b\width) And MY => b\y# And MY < b\y#+b\height Then b\dragged = True


Function updateBoxes()
	MD = MouseDown( 1 )
	MH = MouseHit( 1 )
	MX = MouseX()
	MY = MouseY()
	MXS = MouseXSpeed()
	MYS = MouseYSpeed()
	If MD Then
		For b.box = Each box
			If MH And MX => b\x# And MX < (b\x#+b\width) And MY => b\y# And MY < b\y#+b\height Then b\dragged = True
			If b\dragged Then
				b\x# = b\x# + MXS
				b\y# = b\y# + MYS
			End If
		Next
	Else
		For b.box = Each box
			b\dragged = False
		Next
	End If
End Function
