Can I move player character on navmesh?

I want to block player input and move it’s character to certain point on navmesh. Can I do it without using AI?

Sequencer looks like it’s more for cinematics and cutscenes. I need it for a short action (lie players uses Interaction action, Character goes to the button, Character presses button) and I need for the player not to have control over character when he does it and at the same time having animations working (for walking for example).

It depends on your definition of AI. But, yes, you can have a scripted event do it. The best way probably, was called matinee in UE3 and is Sequencer in UE4.

Here is a link: sequencer

Here is the link for matinee, this might be the best one for you: matinee

The top down template has a full implementation of a Diablo style “click and move to” system.
You should be able to use this system and replace the click action with some other action, replacing the mouse location with whatever location you prefer.

Would that fit your needs?

Yes, that’s why I said the link for matinee would be best for you. I really should have formatted my answer better. Sequencer and Matinee are related. With Matinee you can temporarily take control of a game actor, do what ever you want with it, such as walk somewhere, and then return control back to the player.
