How do I use the Physics Thrusters?

Hi all,
After many hours searching on google, I see that there is no tutorial or even an help page on thrusters (please don’t talk me about this joke wich is the official documentation : Content Examples Sample Project for Unreal Engine | Unreal Engine 5.1 Documentation )…! What ? Nobody explain how does it work ??!
I tried to attach (from 1 to 100) thrusters on my mesh in a blueprint, on an actor on my map, I link them to the mesh, I set auto activated, I add lot (realy a lot) of strength value and it seems… that it just don’t work at all ! Nothing hovering, nothing fly !
I open the content example and I saw the rocket actor and there I don’t know why it’s work . I do all the same in my level and it don’t .
Who could resolve the mistery of the Thrusters !

Hi Komega,

Make sure that the Physics Thruster is the child of the Static Mesh in the Scene Outliner. Also, make sure that the Static Mesh is set to Movable and check Simulate Physics under the Details panel.

I just tested this in 4.2 and it works fine. Just remember the larger the object the more mass it has, so turn the Thrust Strength up as high as you need it.

Thanks, TJ

Hi TJ, I just add a SM_button, I link as children a thruster, SM_button is already a movable mesh, I checked simulate physics (it got a mass of 65 Kg) . I put Strenght over 3000000…nothing move

Ok sorry with auto activated its work

Sorry for muli post (i don’t know how to edit) now I would like to do the same into a blueprint because the actor I need to hover is my player pawn . Do you have sugestions ?

It is doable but using the thrusters could make it very complex (getting just the right amount of thrust for hovering and moving around. You would essentially create a Player Controller, set up all of your components (including the thrusters), and then in the Event Graph make the thrusters Toggle Active on a button push.

Your other option would be to alter one of the standard controllers to simulate a thruster effect.

Here is more info on setting up a character contoller.

And here is also a step by step tutorial on YouTube for setting up a Third Person Blueprint. It’s not exactly what you are doing but the set up is pretty much the same.
