Hi V_Vix,
That launch pad changes the launch velocity based on how high it is placed in the world. (Since it’s getting the location data from arrow component)
I think the best path forward for you will be to take a look at the multitude of youtube tutorials on this subject. (Try a search term like “unreal engine launch pad” )
The most important thing to learn here is how to use the ‘get forward vector’ node for the arrow component.
Hope that helps! Let us know if you have any questions.
