Description

Describe the bug

When a java player collides with a bedrock player, the bedrock player will not move at all, but the java player will be pushed out of the way. I observed this on a PaperMC server, but haven't tested on other softwares.

To Reproduce

  1. If using paper, make sure that enable-player-collisions is set to true in the config
  2. As a java player, try and collide with a bedrock player, you will be pushed out of the way and the bedrock player will stay in place. The same happens if a bedrock player runs into a java player, they will just push the java player out of the way and run right through.

Expected behaviour

Bedrock players can be pushed by colliding with other players.

Research direction
Investigate how Geyser handles player collision between Java and Bedrock editions. Focus on the entity collision handling code, likely in classes related to player movement or entity interaction. Check if the Bedrock player's collision box is being properly applied when pushed by a Java player. Review any existing comments or linked issues for additional context.
