This mod simply let you fly. Only work with keyboard but not gamepad now. I am not a native English speaker so sorry for my language.

Requirement:
ScripthookDRD2 by Alexander Blade (Not the one on Nexus): http://www.dev-c.com/rdr2/scripthookrdr2/
Community ScripthookRDR2.NET: https://www.nexusmods.com/reddeadredemption2/mods/70
All other programs required by the above two programs.

Installation:
Put the "HCL_Superpower_01.cs" into the /scripts/ folder in the RDR2 installed folder (if you have successfully installed the "Community ScripthookRDR2.NET" you should have this folder, if not, you can create one.).

Controls:
Z: Activate/deactivate fly mod.
W: Fly forward when fly mod is activated.
S: Fly backward when fly mod is activated.
A: Fly left when fly mod is activated.
D: Fly right when fly mod is activated.
Space: Fly up when fly mod is activated.
Alt: Fly down when fly mod is activated. (This is the default radar key, of course you need to either change the radar key for the game or change the key binding of this mod.)
F9: During the flying, decrease the flying speed.
F10: During the flying, increase the flying speed.

You can hold W and A to fly left front and so on. When the fly mod is enabled you can see a small blue box at the left of the screen to remind you that you are flying.

How to change key binding:
Open the file with a notepad and make the change according to the instructions inside the area marked with "/// ///////".
If you want to change the fly down key to "Control", just find and chang all "e.Alt" to "e.Control". However, you can only change fly down key to control or shift.

Permissions:
You can do whatever you want with this mod!
