Increase player speed

[Squander12]

I added boots that increase walking speed, in theory everything works, but when I enter the server and try to walk, the server moves me back and gets the following information:
Got position 1.5275054012421543, 79.0, 2.406983900200199
Expected 1.7577250298625335, 79.0, 2.5257922519494524

Client and server code in EntityPlayer
@OverRide
public void moveEntity(double x, double y, double z) {
ItemStack boots = inventory.armorInventory[0];
if(boots != null && boots.getItem() == Item.windBoots) {
x *= 1.9f;
z *= 1.9f;
}

	super.moveEntity(x, y, z);
}

You need to apply the code edits to the server too if you want to make the client & server not desync. Aside from that, if it's still too fast, you might need to disable the speed check in the server code or modify the values it uses.

The code on the server and client sides is the same, it seems to me that the Minecraft beta server has some anti-cheat that teleports me to the previous place.

Yeah, there is a simple one. Ctrl-F for "Expected " and modify the values used to determine if a player is moving too fast.

I found this code in the NetServer Handler class, but I don't know whether to turn it off or change the values.
`playerZ = zPlayer - this.playerEntity.posZ;
distance = deltaStance * deltaStance + playerY * playerY + playerZ * playerZ;
boolean movedWrongly = false;

		if(distance > 1.0D / 16.0D && !this.playerEntity.isSleeping()) {
			movedWrongly = true;
			logger.warning(this.playerEntity.username + " moved wrongly!");
			System.out.println("Got position " + xPlayer + ", " + yPlayer + ", " + zPlayer);
			System.out.println("Expected " + this.playerEntity.posX + ", " + this.playerEntity.posY + ", " + this.playerEntity.posZ);
		}

		this.playerEntity.setPositionAndRotation(xPlayer, yPlayer, zPlayer, yaw, pitch);
		boolean noCollisionsAfterMove = serverWorld.getCollidingBoundingBoxes(this.playerEntity, this.playerEntity.boundingBox.copy().getInsetBoundingBox((double)d, (double)d, (double)d)).size() == 0;
		
		if(noCollisions && (movedWrongly || !noCollisionsAfterMove) && !this.playerEntity.isSleeping()) {
			this.teleportTo(this.lastPosX, this.lastPosY, this.lastPosZ, yaw, pitch);
			return;
		}`

You can change the distance > 1.0D / 16.0D check. The maximum distance a player can move in a single tick according to this code is 0.0625. You'll want to modify it by however much the speed increase is (e.g. 1.5x).

Ok, thanks.
