Limiting a physics object's velocity?

Development Programming & Scripting C++
1

I am quite perplexed on how to limit the velocity of a physics object in UE4. I have done it before in Unity, but I am not finding any equivalent functions in UE4.

I have a Pawn-based class, which creates a physics object the player can control (it’s based off of this tutorial), and I’m not sure how to get the velocity that it currently has, and how to limit said velocity.

Currently, if I keep going in one direction long enough, I’ll gain enough speed to eventually clip through objects! :stuck_out_tongue:

Does anyone have any pointers for me on this? Is the function for getting and setting the maximum velocity named something unclear?

Thank you in advance for any advice! :slight_smile:

Unless you’re using one of the various movement components (CharacterMovement, ProjectileMovement, etc), you’ll need to clamp the speed yourself.



// In your some onTick or some such that is called each frame:
float MyMaximumSpeedValue = 300.0f;
FVector currentVelocity = Mesh->GetPhysicsLinearVelocity();
FVector clampedVelocity = currentVelocity.GetClampedToMaxSize(MyMaximumSpeedValue);
Mesh->SetPhysicsLinearVelocity(clampedVelocity);

Thanks much, @ExtraLifeMatt! That did the trick. :slight_smile:
