FreePie FPS Script by TQwando

Post by Tqwando »

Hi,

I just got my Oculus Rift CV1 and wanted to use a WiiMote and Nunchuck to play FPS games, like Left 4 Dead 2 and Half Life 2 with this
Image.

I tried Tridef, but it does not support headtracking for CV1.
And also tried vireio versions (2/3/4), but they crash on startup with both games.

So I had to buy VorpX to get the 3D effect and headtracking working.
Mouse movement (Head Aiming) is therefore done VorpX.

Anyway I made this FreePIE script, which I currently use for Left 4 Dead 2.
It should be easily editable for other shooters.

Code: Select all

# Author: TQwando
# Description: WII Mote + Nunchuck script for FPS (Currently mapped for Left 4 Dead 2)
# Required: WII Mote (I use it in a one handed gun) + loose Nunchuck (so not zapper)
# Date: 02 June 2016
# Version: 1.0
# How to use:
# 1. Connect wiimote using bluetooth. (assigned wiimote nr does not matter, all are mapped to same keys)
# 2. Script --> Start
# Notes:
# - Nunchuck acceleation sometimes bugged. Check in watch if nunchuck acceleration is showing data, else stop/start script.
# - Motion+ not (yet) needed.

# ==== Controls =====
# -- WII Mote --
# A --> P Key (vorpx anti-motion sickness/zoom out key)
# B --> Left click (fire)
# Dpad --> Arrow Keys (allows for menu navigation)
# Shake up --> r (reload)
# 1 --> enter/return
# 2 --> esc
# Home --> unused
# + --> unused
# - --> unused

# -- Nunchuck --
# Z --> E Key (use)
# Shake up -- > Right click (alt fire)
# Stick --> WASD Keys
# Hold C + Stick:
# - Up --> Wheel up (next weapon)
# - Down -->  Wheel down (previous weapon)
# - Left -->  Middle mouse (scope)
# - Right --> F (flashlight)

# Shake both WII Mote and Nunchuck --> Space (jump)

# ===== TODO =====
# - A wii mote key combination to toggle script running/pauze.
# - Home to reclibrate
# - Wii mote roll left/right perhaps better for Q/E key
# - Jump (space) support by real 'inplace' jump (requires Motion+?)
# - Crouch (c) support by real 'inplace' crouch (requires Motion+?) or hold Nunchuck Z key when roll implemented.
# - Inplace walking enables nunchuck stick to simulate walking. (requires additional wiimote/nunchuck)

# - Wii motion+ movement to mouse for additional aiming (induces sickness?)

# ===== Helper functions =====
# NOTE: 'down' fires button multiple times, pressed fire's only once.

I hope you guys enjoy the script and can help improve it.

Note: This is my first Python script ever :D

I have not reviewed the scrip yet, but how do you solve the issue of having one camera in game and two inputs (CV1 and wiimote). I have experimented with dynamic switching to the wiimote in iron sights mode while the delta between the HMD and wiimote orientation is within a deadzone. The results were quite good.

See early example here https://www.youtube.com/watch?v=GyYm1s6y4RY (much improved now, but no video yet)
