Like i said in the title, i wanted to make a cam like the game parkour on Roblox. But I don't know how. I tried making the head the primary cam but it doesn't work. Thanks. Here is the game BTW. https://www.roblox.com/games/445664957/Parkour
Roblox's cameras use CFrame to manipulate their position and rotation, so if you are unexperienced with CFrames, I'd suggest reading this!
Once you know how to use CFrames, you can manipulate the camera as you wish. To have full control over the camera, set it's type to Scriptable!
