I am creating a blueprint for a sort of “Alternative Friction” which should allow for assigning different friction values to different axis. To test this I have created the blueprint shown in the image. It simply takes the current X velocity of the physics parent and if it’s within a range of -FrictionValue to +FrictionValue it sets the velocity in that direction to zero. The issue I am running into is that nothing seems to happen when it’s run. The function is being called every frame as part of the tick event.
Other information:
-
Target Instance is referring to the chassis of the vehicle. I have tested
adding velocity to it using the same
reference the attached BP image uses
so that shouldn’t be an issue. -
Target Velocity is really just a “Get Velocity (Actor)” node that is
being done outside of the function
for organization purposes. -
I currently have both Friction values set to the maximum values of a
float but it hasn’t changed the
results. -
The friction values of the PhysicsMaterials are all set to 0.0
so that the results will be extremely
clear. The vehicle simply slides
infinitely in any direction no matter
what direction it’s facing. -
I have tried using “Set All Physics Linear Velocity” but it had the same
results.
If I’m going in the completely wrong direction with this solution and there’s a better way to have specific changeable friction values for each axis then I would very much appreciate the input. As you might’ve guessed by the value names this is being used for a “Drifting” system where if the X Velocity gets high enough the friction lowers to simulate losing traction (the IsDrifting Bool). It’s far from realistic but so is the project it’ll be used for.
