How to spawn (projectiles)?
I'm on SFT and I need to know how to spawn projectiles, such as lasers. Spawn as in "place the laser sprite in front of the ship, let it move forward, and animate hit on meteor." Please help.

Re: How to spawn (projectiles)?
Could you be more specific? Are you asking how to shoot?
I'm graduating HS this April and going to college in the Fall.

Re: How to spawn (projectiles)?
Let the laser sprite go to the ship when whatever key pressed. Then let it move 10 steps until it hits the edge or the meteor. On the meteor, make it so that when the laser sprite touches it, it animates. For that, you will have to make different costumes of a meteor exploding and play it when the laser hits.
Hai.

Re: How to spawn (projectiles)?
Do something like this:
Ship's script
<when green flag clicked>
<forever>
<if> <key[ space ]pressed?>
<broadcast[ shoot ]and wait c>
<end>
<end>
Laser's scripts:
<when green flag clicked>
<hide>
<when I receive[ shoot
<go to[ ship
<point in direction( <direction of [ ship ]>
<move( 10 )steps>
<show>
<repeat until> <touching[ edge
<move( 10 )steps>
<end>
<hide>

Ok, should there be a variable to tell when the meteor hits it to "turn it off" so I can't hit it until I restart the game?

Yeah, that's what I'm trying--in a space field. I was being specific; I just didn't tell it in plain English. I guess you could have used something called context clues.

Re: How to spawn (projectiles)?
I mean using the start and stop buttons. Or if my restart button is clicked in the scratch window.

Re: How to spawn (projectiles)?
no, actually the laser can fire multiple times, its the meteors you can only hit once per game.

This project is for shooting projectiles.
As for meteors exploding you have to tell it to wait until touching a bullet and then make it change to an exploding costume and then hide
Can you beat the ever-so challenging Keyboard Khaos?
