Need help creating a diamond shape with highlighted areas!

in General Discussion • Other • 7 months ago

Please help me, I am so confused about this.

If the mouse is in area A or area B, then highlight area E in a color of your choice. If the mouse is in area C or area D, then highlight area F in a color of your choice. Otherwise, highlight areas A, B, C, and D in a color of your choice. The outline of the diamond must always be visible, and you must not draw the line between triangles E and F

Take a look at beginShape() and friends, and at mouseX / mouseY.

This should more than get you started:

void setup() {
size(220, 220);
smooth();
}
void draw() {
background(0);
noStroke();
if ( mouseX + mouseY < 220 ) {
fill(255, 0, 0);
beginShape();
vertex(110, 0);
vertex(220, 0);
vertex(220, 220);
vertex(0, 220);
vertex(0, 110);
endShape();
}
else {
fill(0, 255, 0);
beginShape();
vertex(0, 0);
vertex(110, 0);
vertex(0, 110);
endShape();
}
stroke(255);
line(110, 0, 0, 110);
}
