Hello!

When developing my game, I ran into a problem: How can I properly check the mouse event for my UI? For example if I want to click on the map, then I dont want the game to handle that click, just only the UIHandler. Or closing a window, and in the game the left click is shooting, or casting a spell. Then if I want to close the window, my character shoots a fireball and closes the window. How can I solve this problem?

Send your mouse event to the UI first and make the UI return a true/false value if it handled the event or not. If not, send the event to the game code.

Really good idea. I'll look into it Thanks for help

In the past, I've written game logic to include several screens. You can think of each screen as a layer of updates with the bottom layer being the game level/logic. Input is filtered from the top screen down to the bottom. On input, the screen can choose to handle it accordingly, and/or pass the input along to the one underneath it.

This makes it easy to pop up a 'pause screen' and halt updates to the 'game screen'. Or in your case, create a 'UI screen' and if input was handled, don't pass it down to the 'game screen' - just like Faelenor suggested.
