Wait to everything will ready, and for you pick up the items, click on them! To change the selection of the inventory, use the Number Keys, Click in The Bully to lose your items and for you use the items, click Space Key. This is the inventory, but I'll make more things in future.
If you look the Script of the Game (BB+ Game), you can see how this is works, and I make this but in Scratch, you can see and learn! This inventory uses an old method I used in previous games, in BB+ 2D, it uses a new method, but you can use this outdated version if interested
