Render Rec Tweak

[Rovastar]

Just change a very simple selement to this scene by adding sound reactive movement to the scrolling renders in this scene.

It appears that sounda and soundb are values below and above zero so I have regualted this so you only get possitive values I did this in a very crude way of mysound variable.

if((sounda+soundb)<0) mysound=0; else mysound = sounda+soundb;

simpily if teh left and right channels (I presume a and b are these) are below 0 then make it 0 else add them together.

soundtotal is the movement speed of the top bank of reapeated medusas.

I made it always movement to theright and on biig sound boosts move quicker in the same direction.

soundtotal = soundtotal + 0.025*(1+mysound*mysound);

The bottom set of medusas only moves when there is some sound. This is variable soundtotal

soundtotal2 = soundtotal2 + 0.01*((1+mysound)*(1+mysound)*mysound);

Using multiples of mytest (in a expernational or powers way) to simultae more intense values.

Not much has chnaged but subtle improvements(?). But hopefully displaying the thought process behind tweaking the scenes for other authors.

Feel free to bundle with R4 not really good/changed enough for a sepearate scene.

TEXTURE pic();

MEDUSA med(black,pic);

soundtotal = soundtotal + 0.025*(1+mysound*mysound);
r.count = 40;
o = (frac(soundtotal)*0.5) -1.5;
for (x=0;x<20;x=x+4) {
r.data[x] = o;
r.data[x+1] = 0.5;
r.data[x+2] = o+0.5;
r.data[x+3] = 1.0;
o = o + 0.5;
}
soundtotal2 = soundtotal2 + 0.01*((1+mysound)*(1+mysound)*mysound);
o = (-frac(soundtotal2)*0.5) - 1.0;

r.data[x] = o;
r.data[x+1] = -1.0;
r.data[x+2] = o+0.5;
r.data[x+3] = -0.5;
o = o + 0.5;
}
}

void reset() {}

seems good. If you want to make it different, you could make the rectangles smaller so there's a gap (or maybe pulse with bass)

you could do this with something like:
r.data[x] = o+0.05;
r.data[x+1] = 0.55;
r.data[x+2] = o+0.45;
r.data[x+3] = 0.95;

for the first set, and a similar thing (either adding or subtracting 0.05) for the next.

Infact you could use a feedback as the background so you get recursive rectangles. To do that you'd modify the bit up the top (i removed invert too):

TEXTURE pic();
BUFLOAD bl();
MEDUSA med(bl,pic);
RENDER r(med,med);
BUFSAVE bs(r);

and in the render() section add: bl.handle = bs.handle;

Nice but is it possible to make.

for (y=0;y<24;y=y+1)
for (x=0;x<32;x=x+1) {
m.x[y][x] = ((y%3)-1)*0.01;
m.y[y][x] = ((x%3)-1)*0.01;
m.r[y][x] = 0.8;
m.g[y][x] = 0.8;
m.b[y][x] = 0.8;
}

with any higher 'mesh' then 24 by 32

I tried and it gotr all messed up.

for (y=0;y<24;y=y+1)
for (x=0;x<32;x=x+1) {
m.x[y][x] = sin((y-0.5)*x*2)*0.004 + sin((y-0.5)*x*2.66667)*0.004;
m.y[y][x] = cos((x-0.5)*x*2.666667)*0.003 + cos((x-0.5)*x*2)*0.003;
m.r[y][x] = 0.9;
m.g[y][x] = 0.9;
m.b[y][x] = 0.9;
}

Might look better at 48*64 or above or would teh slowdown be too big.

The module itself will only handle 32x24 - i can make it bigger but i think some people will experience slowdowns - especially on slower PCs. The scripting language isn't massively quick.

When i finally get around to a module SDK i'll include the source to the MAP module, and you can just make a high res version by increasing values.
