pixlyzer-physics

This pixlyzer module runs physics test on minecraft and extracts data from it.

Use cases

• Anti cheat development
• 3rd party clients/servers to not get banned, e.g. integration tests in Minosoft
• Maybe mojang themselves? (check if nothing broke in their messy code)

What affects movement (client side)?

  • walking
  • sprint
  • sneak
  • rotating
  • jumping

Additional entity physics

Ridable entities

(only client controlled)

• strider (with warped fungus on a stick)
• pig (with carrot on a stick)
• all horses (with controls and jumping)
• boat

Client calculated

• items
• projectiles
• firework rockets
• fishing bobber

Non physics things

• client side biome noise
• digging times

About consistency

Tests are general non-mutable, so a diff is possible between versions. New tests can/will always be added, existing tests may only be changed if they break or are considered wrong.

Parkour code (attach debugger in ClientPlayerEntity, where getTutorialManager is called):

"f="+input.pressingForward+",b="+input.pressingBack+",l="+input.pressingLeft+",r="+input.pressingRight+",j="+input.jumping+",sn="+input.sneaking+",sp="+client.options.sprintKey.isPressed()+"  -->   "+getX()+"|"+getY()+"|"+getZ()+"  "+yaw+"|"+pitch
