hey, im trying to make the rocket always point towards the mouse so it looks like its flying in this direction,
have tried other rotate codes to make this work but i can't !
PImage bg;
PImage mi;
int x = 0;
int a =250;
int b =350;
float tx = 0;
float ty = 0;
int dotCount = 10;
float[] xn = new float [dotCount];
float[] yn = new float [dotCount];
//changes speed of ellipses
float[] s = new float [dotCount];
void setup () {
size (1000, 500);
smooth ();
bg = loadImage("stars.jpg");
mi = loadImage("mouse.png");
background(bg);
}
void draw () {
//int i = 0;
int l = 0;
//while (i < dotCount)
{
/*start points of ellipses
xn[l] = (tx+random(60));
yn[l] = (ty+random(150));
s[i] = random (50);
i = i + 1;
}*/
background(bg); //removes smear left by shapes moving
tx += (mouseX-tx)/30.0;
ty += (mouseY-ty)/30.0;
/* fill (169, 40, 146, 100);
int k = 0;
while (k < dotCount) {
ellipse (xn[k], yn[k], 20, 20);
ellipse (xn[l], yn[l], 20, 20);
k = k + 1;
*/
}
image(mi,tx,ty);
/* triangle (tx, ty, tx+100, ty-75, tx+100, ty+75);
fill (169, 40, 146, 75);
triangle (tx+40, ty, tx+80, ty-30, tx+80, ty+30);*/
//triangle (mouseX+100, mouseY+100, mouseX+100,mouseY+150, mouseX+150, mouseY+50);
/* makes ellipses move
xn[k] = xn[k]+s[k];
xn[l] = xn[l]+s[l];
yn[k] = yn[k]+s[k];
yn[l] = yn[l]+s[l];
//makes them keep going accross page.
/*if (xn[k] > tx) {
xn[k] = 0;
}
k = k + 1;
*/
if (xn[l] > tx) {
xn[l] = 0;
}
l = l + 1;
