The trajectory of the arrow at the bow.

Hello everyone!

I made a bow in MCreator, but the bow does not resemble the vanilla bow from minecraft in terms of the shooting system. In minecraft, the titanium is stretched and depending on how much it is stretched, the arrow will fly so far. With a bow made in MCreator, this is not the case, no matter how much I pull the titivu, the arrow always flies along the same trajectory. Does anyone know how to make a bow made in MCreactor look more like a bow from minecraft?
