I found some topics about this problem. But is very much answer and i don't understand what to use for this problem. I have 2 images for players. I want when i press on a image spawn the specific character! I have a football and a basketball image. Please help me to spawn the football or basketball on UNet server when i press on football or on basketball and after press this image, changed to other image on all clients like disabled or used and the other clients can't spawn the same ball! Thx very much!
