Make a sprite shoot a projectile

InsaneMasterDJ

Hello all.
I am fairly new to scratch and need help making my sprite shoot a projectile going in a straight line from where the mouse is pointing. It needs to fire when the player presses the left mouse button. Thanks

I forgot to mention it needs to fire out of a gun, which is attached to my sprite. My sprite main character follows the mouse pointer.

First add a costume to the gun and call it “bullet”, make the bullet look like whatever you like.
Then, on the gun:

when green flag clicked
forever
    
if <mouse down?> then
    
create clone of [myself v]
end

end

Also add this script to your gun.

when I start as a clone
switch costume to [bullet v]
point towards [mouse-pointer v]
repeat until <<touching [edge v] ?> or <touching [ENEMYSPRITENAMEHERE v] ?>>
    
move (10) steps //Change 10 to whatever you like, the higher the number the faster the bullet
end
if <not <touching [edge v] ?>> then
    
broadcast [shot_enemy v]
end
delete this clone

Then to check if the enemy has been shot:

when I receive [shot_enemy v]
...

Well, what i wanna know how you make a sprite shoot to the left side. When you program it, it always shoots to the left side.

Can you share what you have? I'm wondering if you're using a costume facing left rather than telling the firing sprite to point left.

Make a clone, then use the clone as the bullet, and have it repeatedly move in the direction of your choice.

WARNING! THIS IS NOT TESTED!
when green flag clicked
forever
if <mouse down> then
create clone of
end

Then, for the bullet sprite, make a variable called speed.

then say -

set [ speed ] to [1]
when I start as a clone
point towards [ mousepointer]
repeat until <touching edge or (target)>
move ( speed ) steps
if < touching edge or (target)> then
set [ speed ] to [1]
end


Then it will move faster the farther it goes.

Hi, you have forgot to delete the clone or say how to reuse it.

Fine! Another * with a trap. ^^^^

Thank you, but when I switch scenes after shooting the projectiles, they travel with me in a small clump and they make my game lag. The projectiles also move with my main sprite when i move.

There’s a lot of ways to make player/enemy shooting.
Little buggy but simple way is this one:

set [ I shoot from x v] to (x position)
set [ i shoot from y v] to (y position)
create clone of [ bullet v]


when I start as a clone
go to x: (i shoot from x) y: (i shoot from y)

nvm, I didn't see the delete clone component. Thanks a lot for this script.

I doubt this discussion is still active, but for some reason a random bullet follows my mouse, and when I let go it moves the direction it was going. Help?
