How do I get the size of a static mesh?

Basically I have 2 static mesh actors, The first actor can be moved around the map and the second actor follows the first actor at an offset.

To get this offset I need to know the value of size of the first actors static mesh as it can be changed at run time and I don’t want the second actor to ever collide with the first.

So how do I go about getting the first actors static mesh size?

#Actor Bounds, Actor.h

/**
	 *	Returns the bounding box of all components that make up this Actor.
	 *	@param	bOnlyCollidingComponents	If TRUE, will only return the bounding box for components with collision enabled.
	 */
	UFUNCTION(BlueprintCallable, Category="Collision", meta=(FriendlyName = "GetActorBounds"))
	void GetActorBounds(bool bOnlyCollidingComponents, FVector& Origin, FVector& BoxExtent) const;

Thank you so much for the answer. I tried to implement it but the result does not make any sense for me. Could you please lead me about the usage?

The mesh is the one in blue.

Your code is wrong, which is why you are getting bad values. You have:

“Ground Extends x: %d y: %d z: %d”

What you should have is:

“Ground Extends x: %f y: %f z: %f”
