Camel, Horse, Strider #1059

Describe the false positive and how to replicate it

1.Sit on a camel.

  1. Try to jump on it
  2. You will be pushed off the camel

Same with horse (rare) and Strider (especially outside lava)

The jumping code for horses would have to be switched to this for camels

Stepping height must also be set to 1.5 for camels

If the camel refuses to move the camel's horizontal velocity would be set to 0

If you want to support camels, I would suggest decompiling MCP-Reborn to get the 1.20 code to port it over to grim

any news?

I have no idea how to fix this. After experimenting with horses as well, I saw that GRIM sometimes expects Y = 0 from a jump. As for camels, the mojang code is terrible. In my case I just ignore offset if it is less than 2.5 on horses and camels. this is a dumb solution, but it's temporary (see https://github.com/OpenCommunity-Original/Grim/commit/dc68105e0d26766488b98939f0699ca9939353f7).

When will you be pushing these changes and in the mean time is there a way I can disable these checks?

CatTeaA commented 1 year ago

Is there any progress? Looking forward to it

Can confirm that the OpenCommunity-Original fork fork works for me.
