Hi, When I set the x, y coordinates of the sprites on the canvas they locate as if the x, y was the centre of the sprite, not the upper left corner. All my sprite are offset up and to the left from the intended locations. To test this I created a 50 x 50 px dot at 0, 0 on the 300 x 225 px canvas. See screenshot. Which is the correct definition of x & y sprite properties? Thx! ![Screen Shot 2022-09-03 at 3.27.21 PM](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/b/7/b7d8012ba65108f61512fed66c3bd5dbb83e21db.png) ---

As far as I remember, this has always been the case. ---

Maybe I’ve been reading the description wrong. I think Swift uses the centre of the imagesprite, while AI2 uses the top / left corner for 0, 0. I interpreted the Thunkable documentation like the latter.

See this old post talking about the same issue. I know what is written in the docs is not the same but this post will reconfirm my point. > [@Sprite positioning when canvas loads](https://community.thunkable.com/t/sprite-positioning-when-canvas-loads/1327554/4): > > Sprites use the midpoint for coords. If you try to put them half off the canvas, strange things happen. ---

Thanks, I’ll convert my sprite location coordinates to the midpoint. ---

Is this a platform specific issue? Do you see the same behavior on iOS that you do on android? I feel like I’ve used it on iOS in this wasn’t the case but it’s been quite some time ---
