Great mod but you can't really fire a bow with this. You should make some way to have the crosshair permanently stay on the screen.
There are some trade-offs with the system, especially since Minecraft's rendering code is about as mod un-friendly as possible. I can only do so much with code injection without making it a full-time job. Version updates are already nightmarish.
I'm hoping Mojang realizes there is a demand for a more versatile 3rd person camera and they just change their vanilla code.
Great job on this mod. I am currently compiling a modpack, and I would love to add this amazing mod to it. Would you permit me doing so? If you did allow me to use it I would give you full credit for the mod and provide a link to this page in the modpack download.
