I'm using library to create a spin wheel This is link to it What I want to do is add option for the player to spin NO. times and get NO. of prizes at once. so its one click and he gets NO. of prizes and there the normal option of one spin 1 prize which is already available in the game
So, I thought of repeating the function that spins the wheel multiple time and display multiple prizes But I didn't know how to do it. If anyone have an idea of how I can do this.
The function that should be repeated is startspin()
and on click on button NO. spin it should generate NO. prizes
