I have a piece of TNT come out of my character but how do i make it explode.

Probably make an animation and set it so when you drop the bomb the animation plays?

i tried that but it glitched and sent 10 tnt’s come out

Ya and how do i make it destroy blocks

This is harder than you think if you dont know what youre doing. I cant be specific but maybe use the proximity behavior to accomplish this? Someone here may be able to help better.

The simplest way is to make the bomb emit something invisible when exploding, and as pixelstudio said, use the proximity behavior in the block to destroy it.

Thank you luminous and pixelstudios
