dynamic music system (pieterNotSilly's Worklog)
working on my graduation project which will be a dynamic music system 
System working
I had so many distractions last couple of years that i keep procrastinating graduation and everything. I've been working on a graduation project about music that is altered compared to the action that happened on the screen, AKA dynamic music. It's still in an early phase. I've been working on making an engine first. All objects and the music is scripted with lua scripts. In fact the scripts are very easy to work with and test things. I can even change a script on the run. The level editor i worked on has just a few lines of scripting code, most of them initializing code.
Example for a tilemap scroll window
Graphics are done with opengl. All you have to do is place all your graphics numbered in a directory, e.g. tiles\1.png, tiles\2.png and then run "graphicmaker.exe tiles" to make a tiles.pic file that you can use.
Then all a script has to do is for example
The same goes for music scripting where i'll make my dynamic music code(and the actual graduating for me)
I based the programming a bit on div games studio even though some things are bit more complicated because of the way lua works. There are still some extra advantages like placing processes in subgroups where each subgroup has a different function( game paused, main menu, game, level editor ), so it's very easy to program these things compared to div games studio.
A feature i want is that the picture files also contain static 3d models and have them a graphic number assigned to them. The testing game will be a 2D platform game(my favorite game genre).
I'll probably continue working on it even after graduating with a full working engine.
Example for a tilemap scroll window
Code:
map = tilemap:new( 500, 500, 1 )
map:load("mytilemap.map")
g_Scroll[ 0 ].map = map
g_Scroll[ 0 ].active = true
g_Scroll[ 0 ].x1 = 0
g_Scroll[ 0 ].x2 = 640
g_Scroll[ 0 ].y1 = 0
g_Scroll[ 0 ].y2 = 400
g_Scroll[ 0 ].file = loadFile( "tiles.pic" )
g_Scroll[ 0 ].graph = 1 --graph 1 contains all tiles
g_Scroll[ 0 ].tileWidth = 32
g_Scroll[ 0 ].tileHeight = 32
g_Scroll[ 0 ].camera = process:new("player.lua", this )
map:load("mytilemap.map")
g_Scroll[ 0 ].map = map
g_Scroll[ 0 ].active = true
g_Scroll[ 0 ].x1 = 0
g_Scroll[ 0 ].x2 = 640
g_Scroll[ 0 ].y1 = 0
g_Scroll[ 0 ].y2 = 400
g_Scroll[ 0 ].file = loadFile( "tiles.pic" )
g_Scroll[ 0 ].graph = 1 --graph 1 contains all tiles
g_Scroll[ 0 ].tileWidth = 32
g_Scroll[ 0 ].tileHeight = 32
g_Scroll[ 0 ].camera = process:new("player.lua", this )

Then all a script has to do is for example
Code:
this.m_File = loadFile ( "tiles.pic" )
this.m_Graph = 1
function frame()
if ( Mouse.left ) then
this.m_Graph = this.m_Graph + 1
end
if ( Mouse.right ) then
this.m_Graph = this.m_Graph - 1
end
this.m_X = Mouse.x;
this.m_Y = Mouse.y;
end
this.m_Graph = 1
function frame()
if ( Mouse.left ) then
this.m_Graph = this.m_Graph + 1
end
if ( Mouse.right ) then
this.m_Graph = this.m_Graph - 1
end
this.m_X = Mouse.x;
this.m_Y = Mouse.y;
end
The same goes for music scripting where i'll make my dynamic music code(and the actual graduating for me)
Code:
this:playMidiTrack( "test.mid", 1 )
this:ChangeInstrument( MUS_ACOUSTICGUITAR )
while( true ) do
this:noteOn( 80 );
this:wait( 1 );
this:noteOff( 80 );
end
this:ChangeInstrument( MUS_ACOUSTICGUITAR )
while( true ) do
this:noteOn( 80 );
this:wait( 1 );
this:noteOff( 80 );
end

I don't quite understand the concept of dynamic music and also not what exactly is the dynamic part in the piece of code you provided. Could you elaborate a bit?

Good to see you're still alive Pieter! Like Sandman I also wonder about the meaning of 'dynamic music'.

dynamic music is also called adaptive music. Most games use tricks like channel muting or picking different music loops to give you this impression. For example right now the main menu plays a midi and it will increase the tempo if you move the mouse more and will decrease if you don't move the mouse.
I try to go a step further by actually generating a melody.
And the examples are just to give an impression. playing a midi file is not very adaptive :P.

Okay I like the sound (HAHA) of that; could be brilliantly for atmospheric games like in the horror genre.
