I am making a Pet Equip system, but the function is sometimes called 2 times in a way that I don’t know why, which causes it to revert its first job, for example, I click the button while “Equiped” and it becomes “Unequiped”, but although I did not press the button again at this time, the function is called again and this time it does “Equiped” because it is “UnEquiped”, how can I solve it, I am also aware that the code is very long, thank you for reading the code so long. I’m also sorry that I don’t have good english
