I want to make a recoil for my gun, and I partially succeded, however, I can’t make the camera rotate up without setting it to scriptable TL;DR How would I rotate the camera UP while not changing the camera’s cameratype to scriptable?
You need to change the camera to Scriptable, if you still want the player to control it (like it your case), you would have to make custom camera movement.
You’ll need to use RunService. You also have to set the camera to scriptable because if you don’t, the camera will stay focused on the player. It’s recommended that you tween the camera’s rotation for a smooth rotation. Here are links to some APIs that’ll help:
