New CollisionDamage

This mod is a remake of CollisionDamage, originally created by Ultimate_Kevin.
It provides a potion effect called "Collision Damage", but does not include any built-in way to obtain it — players need to create their own method of acquisition according to their needs.

When an entity has the "Collision Damage" potion effect, it deals damage to nearby entities based on its movement speed. Higher speed means greater damage (the minimum speed required to damage entities defaults to 5).

Once speed reaches certain thresholds, the entity can smash through soft blocks such as dirt, sand, and wood (default speed 10) and hard blocks such as stone and ores (default speed 15) in its path.

At even higher speeds, the entity gains a brief period of invincibility, becoming immune to all damage (default speed 20).

All speed thresholds and the damage multiplier can be freely adjusted in the mod's configuration file.
