Hello, I am new to developing with Game Maker, I am French. I am attaching an image of the prototype of the interface that I want to set up. There are 5 sensitive 'zones'. The first consists of a series of discs (which will contain an icon); the second now contains (it can evolve) 4 management buttons; the third contains a selection of one color among 6; the fourth contains two textual information; and the last one, number 5, displays the icon chosen in 1. So much for the description. My question is to find the best solution in Game Maker for such an interface. A set of independent sprites that I position to the nearest pixel. How to give a hover effect when I am over a button (action with the mouse). To be honest, I'm working on a Sokaban type game (old game) and the interface I'm showing you consists of a part of the level creator. Thank you for your answers. Best regards.Jean-François
