hey, i tried to make an advanced mousefollow in which an object flys from a position (vertex) to the mouseposition...
but it doesnt work... whats wrong ?

int posX;
int posY;
int zielX;
int zielY;
float speed = .05;

void setup() {
 size(350, 505);

}

void draw(){
   background(50, 100, 95);
   
zielX = mouseX;
zielY = mouseY;
 
posX += (zielX - posX) * speed;
posY += (zielY - posY) * speed;

pushMatrix();
translate(posX, posY);
fill(150, 137, 76);
beginShape();
vertex(101, 382);
vertex(165, 335);
vertex(165, 458);
vertex(101, 458);
vertex(101, 382);
endShape();
popMatrix();
}


void mousePressed(){
zielX =mouseX;
zielY=mouseY;

}

There is an offset between your shape and posX/posY.
Subtract minimal X value and minimal Y value from the coordinates of the shape:
Code:
pushMatrix();
translate(posX, posY);
fill(150, 137, 76);
beginShape();
vertex(0, 47);
vertex(54, 0);
vertex(54, 123);
vertex(0, 123);
vertex(0, 47);
endShape();
popMatrix();
