In other words, I would like to know how to make it so that when you walk up to the Tool, you can't grab it and the icon does not appear in your hotbar. I've tried several times to do this, but it just won't work out. Can somebody help me?
Just lock the tool/model and it won't allow it to be grabbed. A.K.A: Click the tool/model if "Locked" isn't checked then check it. And done.
He means copy everything in the tool, and put it in a model, and anchor the bricks inside the model so it does not move. Simple.
Just remove the Tool part, and make it into a model. Here, post what you're trying to use into your models, and i'll do it for you.
