"Before you start programming, plan your strategy. Writing this exploding projectile mod is not as difficult as the minigame mod, but you must still design its complex parts.
First, you need to define these two actions to make the block.
Run when you start the mod.
Explode when it lands.
I like Minecraft servers for prison better. You can program much cool stuff there and explosions, among other things.
Once you start your block, you must make it explode when it hits the ground. You can browse LearnToMod's blocks to find a blast creation block in the Minecraft → World category that you can use to make the block explode when it hits the ground."
