blow game_calculating average angle
« on: Nov 21st, 2004, 4:47pm » |

this is sketch of game with serial interface..
this game is based on concept that several people can control the ball position on graphical display through windmills..
game have three inputs- -from BASIC STAMP2 with three pots (in future I 'll raplace pots with windmills)..
so in future this game will be with blow'able interface (five windmills).
these windmills are set around round display.
every windmill's speed is related to its angle equivalent of circle.
if I blow to the first windmill (angle equivalent = 120 degrees; speed= 255) and other windmill speed will be zero.. ball motion direction will be 120 degree and speed = i=i+255////
////several weeks I am calculating how to simulate ball game around round table with blowable control..///
_______________________________________________________
How clearly calculate relations between inputs (speed) and their equivalents (degrees)?

//this is game sketch ,wich represents game concept int e1_size = 20;

float r = 200.0; // radius
float i = 0; //angle
float theta = 0;
int n = 10;
float x,y =0.00; //ball coordinate
float mx = 0.00; //

background (100);
stroke(102);
ellipseMode(CENTER_DIAMETER);
framerate(80);
}
void loop()
{
background (0);
xx = (cos (theta))*r;
yy = (sin (theta))*r;
i=mouseY;// mouseY controls rotational motion
float D = dist( xx, yy, x, y);
float mx = (mouseX -D) /9000.00; /*mouseX controls speed of ball motion */
x= x-mx*xx;
y= y- mx*yy;
if (x/cos(atan2(y,x)) > r&& y/sin(atan2(y,x))>r)
{
x=0;
