FAQ: How can I change how screen resource locations are referenced (top-left vs. center)?
#1
You can define the on-screen position of resources (like text, images, and videos) in one of two ways: by their center coordinates or by their top-left coordinates.
  • Center (Default): The X and Y position values you enter correspond to the exact center of the stimulus.
  • Top-Left: The X and Y position values correspond to the top-left corner of the stimulus. This is especially useful for left-aligning text, as the starting position of a sentence will not shift even if its length changes.
You can change this preference for your entire project by going to Edit menu -> Preferences -> Screen -> Location Type:
   

From there, choose between Center and TopLeft Position.

⚠️ Important: This is a Project-Wide Setting
Please be aware that this is a global setting for your project. It is not possible to use center coordinates for some resources and top-left coordinates for others within the same experiment. Your choice of Center or TopLeft will apply to all stimuli.
