My button won't even highlight on mouse over. I have an EventSystem. Tried with the EventSystem option Force Module Active. I have only one Canvas. The Canvas has a Graphic Raycaster component. Canvas Render Mode is set to Screen Space - Overlay, also tried the other two with the camera, didn't work. The button is a child object of the Canvas. The button is marked as interactable and calls a function from a script. There are no other HUD objects that are at the same place as the button. I've added using UnityEngine.EventSystem; to my script. Tried putting the button on different places in the hierarchy. Tried playing the game and restarting Unity a couple of times. There are a few more things I've tried for sure, can't remember everything at the moment.. getting desperate already.
