# Collision with Abstract Entity

edited December 2017

I made an L shape, was wondering if I could some how make a collision with it. I used vertexes to make the shape for example.

``````beginShape();
vertex(20, 20);
vertex(100, 20);
vertex(100, 35);
vertex(35, 35);
vertex(35, 100);
vertex(20, 100);
vertex(20, 20);
endShape();
``````

This is the method I used up above to make the L shape. Was wondering if I could make a simple collision with it, like this easy game for example.

``````float bullX = 20;
float bullY = 165;
float targX = 500;
float targY = 150;
float spd = 7;
color targColour;
int countX = 0;
int countY = 0;
int dirCount = 0;
int dir = 1;
void setup () {
size (800, 400);
targColour = color (random (100, 255), random (100, 255), random (100, 255));
}
void draw () {
background (0);
countX++;
countY++;
dirCount++;
fill (#FF0303);
rect (bullX, bullY, 20, 5);
if (countY == 10) {
countY = 0;
targY = targY + random (5, 8) * dir;
}
if (dirCount > 130) {
dir = dir * -1;
dirCount = 0;
}
if (targY < 0) targY = 0;
if (targY > height - 13) targY = height - 13;
bullX = bullX + spd;

if (bullX + 20  >= targX && bullX + 20 <= targX + 50 && bullY <= targY + 40 && bullY + 5 >= targY) {
spd = 0;
targColour = color (random (100, 255), random (100, 255), random (100, 255));
}
fill ( targColour);
rect (targX, targY, 50, 40);
if (spd == 0 || bullX > width) {
bullX = 0;
spd = 7;
}
}

void keyPressed() {
if (key == CODED) {
if (keyCode == UP) {
if (bullY > 0) {
bullY = bullY - 5;
}
}
if (keyCode == DOWN) {
if (bullY < height - 5) {
bullY = bullY + 5;
}
}
}
}
``````

Thank you in advance for the help!
