Player can't teleport (Moved wrongly) [MC 1.15.2]

Hello,

my idea was to create just a simple teleporter mod that is able to teleport a player to another position in Minecraft 1.15.2. I created the teleporter successfully but it just can't teleport

because when the teleporting code was executed there is a warning in the log that sais: "[minecraft/ServerPlayNetHandler]: Player moved wrongly!" and does'nt teleport. First I used the following code:

entity.setPosition(connectedTeleporterPos.getX(), connectedTeleporterPos.getY(), connectedTeleporterPos.getZ());

where "entity" is the instance of Entity that I'd like to teleport and "connectedTeleporterPos" is the target teleport position.

Because the problem only occures in multiplayer I thought I could fix the issue by using the following code:

((ServerPlayerEntity)entity).connection.setPlayerLocation(connectedTeleporterPos.getX(), connectedTeleporterPos.getY(), connectedTeleporterPos.getZ(), 0, 0);

but it fixed nothing.

 

Does anybody have an idea how to solve this problem?

Thank you in advance.

Please post more of your code.

Make sure you are teleporting the player on the server.

Some tips:

1. Do not follow tutorials on YouTube, especially TechnoVision (previously called Loremaster) and HarryTalks, due to their promotion of bad practice and usage of outdated code.

2. Always post your code.

3. Never copy and paste code. You won't learn anything from doing that.

4.

Programming via Eclipse's hotfixes will get you nowhere

5. Learn to use your IDE, especially the debugger.

The "picture that's worth 1000 words" only works if there's an obvious problem or a freehand red circle around it.

1. Read the EAQ before asking for help. Remember to provide the appropriate log(s).

2. Versions below 1.11 are no longer supported due to their age. Update to a modern version of Minecraft to receive support.

Ok I solved this. The problem was that the player moved to fast. The following code is from ServerPlayNetHandler that blocked my teleport:

if (!this.player.isInvulnerableDimensionChange() && d11 > 0.0625D && !this.player.isSleeping() && !this.player.interactionManager.isCreative() && this.player.interactionManager.getGameType() != GameType.SPECTATOR) {
	flag = true;
    LOGGER.warn("{} moved wrongly!", (Object)this.player.getName().getString());
}

d11 is proportional to the distance walked since the last tick so I modified d11 indirectly by setting players posX, posY and posZ variables and sending a CPlayerPacket with the new position to ServerPlayNetHandler#processPlayer function to validate the new position from server's side.

I know it's not the best solution, but it works fine.

Thank you nevertheless for your help @DavidM!
