gideros find relative coordinates of sprite

Here’s the picture of elem. I'm drawing a kind of sequence diagram but I don't want to calculate every position. If you scroll the page and repeat, you’ll notice that as window-relative button position changes, its window coordinates ( y/top/bottom if you scroll vertically) change as well.

• left/right – X-coordinate for the left/right rectangle edge.įor instance click this button to see its window coordinates: I would use s.setPosition (x, y) and then s.draw (batch) which uses the sprite's set position and size You can find out if your mouse is over the sprite with the following if ( () > s.getX () & () < s.getX + s.getWidth () & () > s.getY () & () < s.getY + s. gideros find relative coordinates of sprite

top/bottom – Y-coordinate for the top/bottom rectangle edge,.width/height – width/height of the rectangle (can be negative).Īdditionally, there are derived properties:.x/y – X/Y-coordinates of the rectangle origin relative to window,.If you want the sprite to rotate, you can set imageangle direction. If you only change an instance’s direction, it will move in that direction but the sprite will continue to be drawn with its orientation unchanged. The method elem.getBoundingClientRect() returns window coordinates for a minimal rectangle that encloses elem as an object of built-in DOMRect class. Related to direction is imageangle, which is a built-in GML variable that is used to rotate the sprite belonging to an instance. clientY – window-relative coordinate did change (the arrow became shorter), as the same point became closer to window top.Įlement coordinates: getBoundingClientRect.pageY – document-relative coordinate stayed the same, it’s counted from the document top (now scrolled out).
