UE5 Wheelbarrow Physics Setup With Player Attachment

Hi guys,

Just wanted to get some help please

I have a wheelbarrow attached with the player, inside the wheelbarrow there are boxes and spheres using real-time physics simulation.

What is the best way to set this up in UE 5 so that:

  • The wheelbarrow follows the player properly
  • The physics objects stay inside naturally
  • The objects react realistically while moving
  • The wheelbarrow movement does not break or glitch the physics simulation

What is the recommended workflow for this kind of setup?

If the wheelbarrow is already in the character BP, then just connect them with a physics constraint, set the angular and twist limits “to taste,” and maybe add a leaning transform to the wheelbarrow when the character turns. You may need to restrict the character’s sideways movement to prevent full 45+ degree turns, however.

Conversely, you could allow the player to instead control the wheelbarrow, pulling the character behind it with the same physics constraint relationship mentioned above. You would just need to handle any transitions between lone character and wheelbarrow plus character–hide/unhide meshes or spawn/destroy actors. In this scenario, the character is lame, merely moving in-place according to its ABP, while the wheelbarrow provides the actual translation.

In either case, using IK would allow you to keep the character’s hands attached to the wheelbarrow’s handles.

Lastly, the objects in the wheelbarrow would take care of themselves, using standard physics.

Take a look at the UE vehicle template for “car” movement and a youtube physics constraint tutorial for ideas/guidance. The UE free content examples also cover a bit of each subject.

Hi,

Thank you so much for your humble solution. I will try that.

Also, I just realized that I didn’t connect the wheelbarrow with the player correctly.

Can you also please advise me on how I can do that as well?

I’m learning along the way, so please bear with my noob questions.

Thank you!

How you attach the player to the wheelbarrow, or vice versa, depends on the method you intend to use:

Player drives character (pushes wheelbarrow):

Player drives wheelbarrow (pulls character):

Thank You So Much for the advice. Really Appreciate it!
