Introduction

MCreator is a powerful tool for creating custom Minecraft mods, allowing users to create a wide range of content, from simple items to complex machines. However, like any software, MCreator is not immune to bugs and issues. In this article, we will explore a specific problem that has been reported by users, where the custom projectile's hitbox does not interact correctly with blocks.

Issue Description

The issue is fairly simple to understand. When you change the custom projectile's hitbox, it seems that the interaction with blocks does not work. It works fine for entities, but the hitbox seems to go through the block and only registers a hit when it is actually at the middle of the hitbox. Therefore, when half of the hitbox goes through blocks, it just phases inside the blocks it encounters as if nothing were there.

This issue can be observed in the following screenshots:
