AI Agent Walk Backward facing Player

[serenity]

I need the AI NavMesh Agent to walk backwards for a couple meters when too close to the player while still facing the player.

I have read in the following page that its better to use SetCharacterMovementInput & SetCharacterDeltaYawRotation to move the AI:

Artificial Intelligence (AI) - Opsive

The Ultimate Character Controller is focused on being a great character controller so it does not include any built-in AI implementations. AI is an extremely . . .

opsive.com

Something like this:

KinematicObjectManager.SetCharacterMovementInput(_character.KinematicObjectIndex, 0, 1);
KinematicObjectManager.SetCharacterDeltaYawRotation(_character.KinematicObjectIndex, 1);

1) Is the above used alone or it has to be coupled with setting the destination as well as such:

agent.destination = player.transform.position;

2) What does the range of values for horizontal and forward movement do (-1 to 1)?

3) Will these actions sync over the network using the Pun Addon?

Thanks

1. If you're using a NavMeshAgent then you do not need to manually set the CharacterMovement/Rotation.
2. Yes, it is -1 to 1. This simulates a button press.
3. If you are setting this on the master client and the master client owns the AI then it will.

So how would you make the AI go backwards while still facing the player? Does the move type has anything to do with it? I am using 3rd person controller with adventure mode.

How do you set it to the master client and do you have to pass that to a different client when master client leaves session?

The adventure movement type will always move the character forward. In that case the combat movement type will allow the character to move backwards.

How do you set it to the master client and do you have to pass that to a different client when master client leaves session?

The master client is normally the first person to join the room. When the master client leaves you will need to switch to a different client. This is on the Photon side of things though so I would take a look at their documentation for how it's done.

I changed AI agent to combat but it keeps turning its back to player when backing away even though I have LookSource set to player.
Any other setting that has to be set

Thanks I will check it

Could it be the NavMeshAgent rotating the character?

AI strafe while aiming, code change recommendation

Maybe you want to change those lines in your next update, so it is easy to get the enemy AI-character moving in all directions while aiming: at the script "NavMeshAgentMovement" at Line Nr 70, inside the IF with the comment "// Only move if a path exists." From...

opsive.com

After you make this change you'll need to tell the NavMeshAgent not to update the rotation.
