Bedrock crawling behavior inconsistent with java, allows sprint-crawling #2740

Open ChiboYen opened 2 years ago

ChiboYen commented 2 years ago

Describe the bug

Bedrock crawling behavior is inconsistent with Java Editon, because a Bedrock player can in certain cases, sprint-crawl. This is an issue because it can trigger anticheats falsely or give the Bedrock player an advantage.

To Reproduce

Expected behaviour

Java players can only crawl at the normal slow speed, there is no other speed. Bedrock should have this behavior.

The main problem from an anti cheat point of view isn't that this is possible, but that the player is incorrectly reported as not sprinting. Preventing this behavior from the Bedrock client would probably be ideal for consistency with Java, but alternatively just reporting the flag correctly should fix any issues with anti cheats.

Given that cheating on Bedrock edition is far less likely than on Java, giving Bedrock players bypass perms for the anticheat is usually the recommended action. I personally love the idea of seeing a player spring crawling towards me :)

This will be fixed if possible. I did encounter it a bit before break - I believe it's some sort of regression since I don't remember this happening before; otherwise, it's a Bedrock client issue.

Bedrock hacked clients and cheats do exist, I don't believe you were aware of this. Themis is an anticheat specifically with Bedrock in mind. I thank Camotoy for prioritizing the consistency between java and bedrock.

Is this still an issue?
