2b2t is the king of anarchy servers in the eyes of many in the Minecraft community. The server is synonymous with the culture at this point and almost defines the genre altogether. There are absolutely zero rules in what is often humorously described as the "oldest anarchy server in Minecraft" by the community. The server also features a huge selection of some serious YouTube names who have claimed 2b2t as their home, including the likes of FitMC and Salc1. 2b2t is an absolute must-try for any players wanting to get their feet wet in the ruthlessly intense world of pure anarchy servers. The only slight downside to this server is the ridiculously long queue times in place due to its unparalleled recent success and popularity. -
I'm trying to make a block that is slippery in one direction: its friction depends on the angle of your motion. I've got it to work perfectly for nonplayer entities, but (once again), the player poses a different issue because of siding. My testing indicates that calling getDeltaMovement is giving (0, -1, 0) on serverside when it shouldn't be, and this screws up the calculation. How can I get accurate information here? @Override public float getFriction(BlockState state, LevelReader level, BlockPos pos, @org.jetbrains.annotations.Nullable Entity entity) { if (entity == null) { return 0.7F; } //Get a unit vector in the appropriate direction Vec3 axisUnitVector = Vec3.ZERO; if (state.getValue(AXIS) == Direction.Axis.X) { axisUnitVector = new Vec3(1, 0, 0); } else if (state.getValue(AXIS) == Direction.Axis.Z) { axisUnitVector = new Vec3(0, 0, 1); } //The block can't be placed vertically //Take the dot product of that vector with a unit vector in the direction of the entity's movement //This effectively just returns the cosine of the angle between the entity's vector and the chosen axis //i.e. 0 when perpendicular, 1 when parallel, etc. Vec3 normalizedMovement = entity.getDeltaMovement().normalize(); double dotProduct = Math.abs(normalizedMovement.dot(axisUnitVector)); //Produce a string for reporting String vectorString = "(" + StringUtils.truncate(String.valueOf(normalizedMovement.x), 4) + "," + StringUtils.truncate(String.valueOf(normalizedMovement.y), 4) + "," + StringUtils.truncate(String.valueOf(normalizedMovement.z), 4) + ")"; //Friction ranges from 0.6 to 1 depending on that cosine double finalMultiplier = Mth.lerp(dotProduct, 0.6, 1); chatPrint("Friction: " + StringUtils.truncate(String.valueOf(finalMultiplier), 5) + ", dot:" + StringUtils.truncate(String.valueOf(dotProduct), 5) + ", vector:" + vectorString + (level.isClientSide() ? "clientside" : "serverside"), (Level) level); return (float) finalMultiplier; } Walking on the block in the slippery direction produces this output: [CHAT] Friction: 0.6, dot:0.0, vector:(0.0,-1.0,0.0) serverside [CHAT] Friction: 0.981, dot:0.953, vector:(-0.0,-0.3,-0.9) clientside [CHAT] Friction: 0.6, dot:0.0, vector:(0.0,-1.0,0.0) serverside [CHAT] Friction: 0.981, dot:0.952, vector:(-0.0,-0.3,-0.9) clientside [CHAT] Friction: 0.6, dot:0.0, vector:(0.0,-1.0,0.0) serverside [CHAT] Friction: 0.981, dot:0.952, vector:(-0.0,-0.3,-0.9) clientside [CHAT] Friction: 0.6, dot:0.0, vector:(0.0,-1.0,0.0) serverside [CHAT] Friction: 0.981, dot:0.952, vector:(-0.0,-0.3,-0.9) clientside [CHAT] Friction: 0.6, dot:0.0, vector:(0.0,-1.0,0.0) serverside [CHAT] Friction: 0.980, dot:0.952, vector:(-0.0,-0.3,-0.9) clientside [CHAT] Friction: 0.6, dot:0.0, vector:(0.0,-1.0,0.0) serverside [CHAT] Friction: 0.980, dot:0.952, vector:(-0.0,-0.3,-0.9) clientside [CHAT] Friction: 0.6, dot:0.0, vector:(0.0,-1.0,0.0) serverside [CHAT] Friction: 0.980, dot:0.952, vector:(-0.0,-0.3,-0.9) clientside -
