<![CDATA[Do touch coordinates change when the screen is moved?]]>@Murtaza if you touch an object and then move the screen, will the coordinates for the touch behavior be different when the screen moves?

X=Touching.X(World Coords)-Screen.X+16
Y=Touching.Y(World Coords)-Screen.Y+12
When you change the zoom, this won't work anymore since the screen centre would change. To fix this, change the 16 and 12 offsets to the centre of the screen when you zoom.

I assumed you were talking about touches using global behaviours. When turning off world coordinates, it outputs the position relative to itself.

eg. you have a blue box in the middle of the screen and you output the y coordinates of the finger with world coordinates off. As soon as your finger goes under neath the blue box, it will be less than zero. If your finger goes above the blue box, it will output the the height of the blue box + the distance away from the edge of the blue box.

And tell me what you expect to happen and what is happening?

Thanks.

Turning it off returns where you touched, relative to the object you are touching. To get the screen coordinates, subtract the touching world coordinates from the screen position and add the screen offset (by default, 16 to x and 12 to y).

There is only a toggle for world coordinates, or does turning that off make it screen coordinates? Even with world coordinates off I still have the same problem.

Screen coordinates will be the same, world coordinates will be different. So if you have world coordinates selected then that is how it should be working.

Can you either share a link to your project or post a screenshot of the behaviours?

I had the while touching behavior set a label to the the touch point (world coordinates on) and then when i touched the object it would move the screen. When i played it i touched the object, and the coordinates where i touched were not what it showed.

If the switch is set to use screen coordinates then it does change.
