FLY SYSTEM
FLY LIKE AN EAGLE WITHOUT REDBULL :D
-- DEMO SCENE NOT INCLUDED --
Hey guys,
as many of you have requested, now you can finally fly over the clouds and further.
Please let me know, if you like it and don't hesitate to report issues.
I'll continue to work on this addon to improve it over time, so stay tuned!
Cheers, sickscore
FEATURES:
- Default falling/landing animations when out of stamina/grounded/crash-landed
- Stamina consumption for flying / floating mid-air
- Controllable forward and up/down force
- Custom collider size for flying state
- Free mocap animations included
- ..etc..
HOW TO USE:
- Press "X" while jumping to enter flying state.
- Hold down "space" or "left shift" to fly upwards/downwards
=> You can change the keybinds in the Invector input manager
INSTRUCTIONS:
1. Download unitypackage with free mocap animations and a template how to setup the animator controller -> DOWNLOAD
2. Backup original files and apply the code changes from below
KNOWN BUGS:
- T.B.A.

vThirdPersonInput.cs
Add 3 additional GenericInputs under Variables => Default Inputs
public GenericInput flyInput = new GenericInput("X", "X", "X");
public GenericInput flyUpInput = new GenericInput("Space", "X", "X");
public GenericInput flyDownInput = new GenericInput("LeftShift", "X", "X");Add FlyAirControl method call to FixedUpdate after cc.AirControl()
cc.FlyAirControl ();Add FlyInput method call after JumpInput()
FlyInput ();Add FlyInput method (after JumpInput method = line 240)
protected virtual void FlyInput ()

if (flyInput.GetButtonDown ())
