I need help adding grappling

Hi @luke and welcome,

For a grappling mechanic, you would have to use spring joints, you can look at this tutorial to learn how to use joints from Ammo in Playcanvas, PlayCanvas 3D HTML5 Game Engine
There is no example project having a spring joint or grappling mechanic which I can think of, but by doing a quick search on youtube, I see many tutorials to make this mechanic in Unity, which should help you to make it in Playcanvas.
