Excited warfare on the seas of a Kepler IV.

The time has come to conquer Kepler IV. Check video.

Compiling and Installation

'Requirements'

• ODE: Open Dynamics Engine, version 0.14: https://bitbucket.org/odedevs/ode
• Please this README or the guidelines in http://ode-wiki.org/wiki/index.php?title=Manual:_Install_and_Use to install ODE on your Macbook.

make ./waku

That's all folks.

ODE 0.14 Compilation on Mac Sierra

• Run the following script to install automake tools for Mac

#!/bin/sh

##
# Install autoconf, automake and libtool smoothly on Mac OS X.
# Newer versions of these libraries are available and may work better on OS X
#
# This script is originally from http://jsdelfino.blogspot.com.au/2012/08/autoconf-and-automake-on-mac-os-x.html
#

export build=~/devtools # or wherever you'd like to build
mkdir -p $build

##
# Autoconf
# http://ftpmirror.gnu.org/autoconf

cd $build
curl -OL http://ftpmirror.gnu.org/autoconf/autoconf-2.69.tar.gz
tar xzf autoconf-2.69.tar.gz
cd autoconf-2.69
./configure --prefix=/usr/local
make
sudo make install
export PATH=$PATH:/usr/local/bin

##
# Automake
# http://ftpmirror.gnu.org/automake

cd $build
curl -OL http://ftpmirror.gnu.org/automake/automake-1.15.tar.gz
tar xzf automake-1.15.tar.gz
cd automake-1.15
./configure --prefix=/usr/local
make
sudo make install

##
# Libtool
# http://ftpmirror.gnu.org/libtool

cd $build
curl -OL http://ftpmirror.gnu.org/libtool/libtool-2.4.6.tar.gz
tar xzf libtool-2.4.6.tar.gz
cd libtool-2.4.6
./configure --prefix=/usr/local
make
sudo make install

echo "Installation complete."

• Now download the ode-0.14.tar tarball.
• Modify LIBTOOLIZE variables from 'glibtoolize' to 'libtoolize'
• ./bootstrap
• ./configure
• make clean && make && sudo make install

Next steps

• Resolve issues: the open architecture based on ODE generates too many glitches in the game. In such a way, the game has too many degrees of freedom that needs to be constrained.

Issues and missing stuff

• Floor is working great.
  • However, the floor is squared so when you fly high you see that the horizon changes weirdly. Need improvement.
  • Sea is good.
  • Sky must be improved.
• Island generation works very good.
  • The engine is calculating the islands perfectly.
  • Islands are BMP heightmaps 60x60. These values are hardcoded to 600x600 in the model.
  • Max height (255) is 60. Hardcoded.
  • Island floor, which can be less than zero, or greater than zero, need to be adjusted manually for each island. Need improvement.
• Collision detection has been improved.
  • Island heights works PERFECT for Walrus. It is amazing how well they work.
• 3DS Engine has been incorporated so I can now use 3DS models!!!!
• Walrus mechanics works but can be improved, and the texture of the Walrus is broken again.
  • Walrus control, although it works, can be improved also.
• New library for sound-support.
  • I am using TEMPORARILY system calls and afplay.
• Manta
  • The FDM model from Flight Simulator works but it is very difficult to really control it. And there are many parameters.
  • I implemented a new mixed model which handle the forces form the dynamic model but keep the airplane pose based on a simplified model (not dynamic). I will move from here which is very good for control (and automation).
• UserControl can be improved. Sensitivity must be adjusted from within the game.

Blender

• Shift+Ctrl+Alt+C -> origin to geometry
• N: dimensions

Sounds

• ffmpeg -i input.m4a output.wav
• ./playaudio hellosine.wav 44100 1.0
