Hi.

First of a big thanks to "jbum" who have helped me with half of my coding..

Now...

I have a comet (komet.png) that I'm throwing at earth (earth.png)

On collision i want my comet to disapear and display tha word BOOOM

on the impact location.

For the moment Im sending the comet outside the screen, but I assume it will create LAG

when I spawn more and more comets...

How do I erase or kill an object in a simple way (on impact:) and can I do this in just "void collision"?

looks like this right now:

void collision(){

if ( dist(x, y, i1, i2) < i3) {

println("hit");

// x = 1000000;

// y = 1000000;

i++;

Font2 = loadFont("PressStartK-12.vlw");

textFont(Font,12);

text("BOOOM",x,y);

}

just put a switch in your if statement that turns a boolean variable from true to false. something like this should work e.g.

boolean showComet;

void setup () {

showComet = true;

}

void draw () {
if (showComet) {
// function for displaying and moving comet image
}
}

void collision(){

if ( dist(x, y, i1, i2) < i3) {

showComet =! showComet

println("hit");

// x = 1000000;

// y = 1000000;

i++;

Font2 = loadFont("PressStartK-12.vlw");

textFont(Font,12);

text("BOOOM",x,y);

}

just found your old post. put the if statement here:

void smart(){
movement();
if (showComet) {
kometer();
}
collision();
}
}

Acually it's not working correctly so I'm wondering if I missed something!

I put this in my sketch;

boolean showComet;

void setup () {

showComet = true;

}

and this;

void draw () {

if (showComet) {
// function for displaying and moving comet image
}
}

I rewrote it like this in my class;

void smart(){
movement();
if (showComet) {
kometer();
}

and then finally this at the bottom :

void collision(){

if ( dist(x, y, i1, i2) < i3) {

showComet =! showComet

println("hit");

// x = 1000000;

// y = 1000000;

i++;

Font2 = loadFont("PressStartK-12.vlw");

textFont(Font,12);

text("BOOOM",x,y);

}

collision();
}
}

But It's not working, can you tell me what I did wrong?? Thank you guys!
