Great article. I just wish they would give resellers the same SSH controls versus trying to bleed them dry at $10 a pop per sub-account.

Comment on Creating a Asteroids Flash Game Part 5: Creating and Firing bullets, and making objects “wrap around” the screen by Chris Moeller

The code to delete them is:

if (current_time-bullets[i].life > bullets_max_life)
bullets_to_delete.push(i);

and:
bullets.splice(bullets_to_delete[j], 1);

so to check what is going wrong, you can trace out the values to see what they are, such as above the ‘if’ statement:

trace(“ bullet age: “+(current_time-bullets[i].life+” , bullets_max_life: “+bullets_max_life);

so then you have to check if the bullet age is increasing like it should, or if the max life is accidentally set very high. When the bullet is older than the life, it will splice them out of the array, and they won’t be able to render any more.

I am wondering then if I am having the same issue on part of this.
For some reason my bullets are never deleting. If I shoot,
they continue to trail across the screen indefinitly
until I close the game. The code I see on my end while
doing the tutorial is:

if (CheckKeyDown(SPACE) && current_time-last_fired > firing_delay)

Not sure if thats what is causing the issue, but I get no
syntax errors, and the game starts fine up to this point.

Done writing my algorithm, here’s a thread w/ the code and a picture.

Now that I think about it, would it be possible to increase asteroid variety by flipping the 2 sprites we’ve already coded in? 2(number of asteroid sprites) * 2(whether or not they are flipped horizontally) * 2(whether or not they are flipped vertically) = 8, 6 more sprites than before.

Sorry, I was unclear. I did not mean the asteroids’ sprites, i meant their stats, as depicted by my code. Now that you mention it though, randomly generating the asteroid sprites sounds cool. I think I’ll try it out.

Cool, you’ll have to show your asteroids when you’re finished!

Hello. I wrote a procedural generation algorithm(that is the correct term, right?) for the asteroids!

for (var i:int = thelevel2 + 3; i >= 0; i–)
{
asteroids.push(new asteroid(
archetect.width / (Math.floor(1 + (Math.random() * 5))),
archetect.height / (Math.floor(1 + (Math.random() * 5))),
0,
Math.floor(Math.random() * 4),
Math.floor(Math.random() * 2))
);
}

Hi, I figured out a way to highlight the collision points to help with changing them once I add my own graphics in. Here’s the code:

public function highlightcollisionpts():void
{
collisionptsvis = new Sprite();
collisionptsvis.graphics.lineStyle(2, 0xFFFFFF)
for (var i:int = collisionpts.length — 1; i >= 0; i–)
{
collisionptsvis.graphics.drawRect(collisionpts[i].x, collisionpts[i].y, 2, 2);
}
Game.archetect.draw(collisionptsvis);
}
