How to disable mantling for certain actor? Preferably through tags or collision preset

How to disable mantling for certain actor like a barrel?

i have a barrel that is destructible. I want it to be an object that can’t be climbed/mantled on. How do i stop mantling it when i press jump or fall close to it in its direction ?

i want to disable mantling for certain actors which other wise are mantleable by default

i tried messing around with mantleComponent c++ file but failed to get it right. I mostly eould like it to check for collision type and if it is of type “NoMantle” (i made this collision preset up) the mantle will cancel

You can see from the code above that the mantle system use the profile "IgnoreOnlyPawn" to detect a mantleable object.

If you made a custom collision object channel "NoMantle", you can set the IgnoreOnlyPawn Preset to ignore the objects from the NoMantle object channel as well (in the Engine - Collision category found in the project settings)
It will work because the Mantle system will not see it when looking for a mantleable object.
I found one limitation: if there is a mantleable object under this non mantleable object (for example a non mantleable box on a mantleable box) the trace will go through the first object and detect this mantleable object underneath and the mantle will trigger on the non mantleable object.

Alternatively - the "tags" way:

To disable mantling via tags, you can add the following code to the ALSMantleComponent.cpp, right under the code pasted above

UPrimitiveComponent* HitComponent = HitResult.GetComponent();
if (HitComponent)
{
   if (HitComponent->ComponentHasTag("NoMantle"))
   	return false;
}

Then, in the editor, select the object you want to be non mantleable and add the Component Tag "NoMantle" in the Details panel of this object.
For this to work, even if there is a mantleable object under this non mantleable object, the trace has to detect this object, so don't set the collision object type of this object to Pawn nor Vehicle or antyhing else invisble to the "IgnoreOnlyPawn" Collision Profile.

This is exactly what i needed thank you!
