I'm working on a little thing where I point to a sprite and the sprite is outlined. But when I change the view offset, everything gets, well offset. I use ScreenToWorldX and Y but something isn't taking this in to consideration for some reason.

What am I doing wrong?

+ Code Snippet

activeTile = GetSpriteHit(ScreenToWorldX(GetPointerX()), ScreenToWorldY(GetPointerY()))
	If activeTile > 0
		TX# = GetSpriteX(activeTile)
		TY# = GetSpriteY(activeTile)
		TW# = GetSpriteWidth(activeTile)
		TH# = GetSpriteHeight(activeTile)
		DrawBox(TX# + viewOffsetX#, TY#, viewOffsetX# + TX# + TW#, TY# + TH#, MakeColor(163, 73, 164), MakeColor(163, 73, 164), MakeColor(163, 73, 164), MakeColor(163, 73, 164), 0)
	EndIf

Try this:

+ Code Snippet

activeTile = GetSpriteHit(ScreenToWorldX(GetPointerX()), ScreenToWorldY(GetPointerY()))
	If activeTile > 0
		TX# = WorldToScreenX(GetSpriteX(activeTile))
		TY# = WorldToScreenY(GetSpriteY(activeTile))
		TW# = GetSpriteWidth(activeTile)
		TH# = GetSpriteHeight(activeTile)
		DrawBox(TX#, TY#, TX# + TW#, TY# + TH#, MakeColor(163, 73, 164), MakeColor(163, 73, 164), MakeColor(163, 73, 164), MakeColor(163, 73, 164), 0)
	EndIf

If you are setting the View Zoom too you will need to divide the width/height of the box by the zoom factor too.
