[HELP] Shoot in one direction at a time

Hi, I'm making a basic game in Love where the player can shoot bullets at enemies.
I'm trying to restrict the player to shooting in one direction at a time so the player can't spam bullets in all directions. Here's the part of the code I need modified:
Code: Select all
function player.shoot(key)
if gameState == "playing" then
if key == 'up' then
bullet.spawn(player.x - bullet.width/2, player.y - player.height - bullet.height, 'up')
TEsound.play("/res/shoot.mp3")
end
if key == 'down' then
bullet.spawn(player.x - bullet.width/2, player.y + player.height + bullet.height, 'down')
TEsound.play("/res/shoot.mp3")
end
if key == 'right' then
bullet.spawn(player.x + player.width + bullet.width, player.y - bullet.width/2, 'right')
TEsound.play("/res/shoot.mp3")
end
if key == 'left' then
bullet.spawn(player.x - player.width - bullet.width, player.y - bullet.width/2, 'left')
TEsound.play("/res/shoot.mp3")
end
end
end
Any help would be very much appreciated!

Make a variable called "player.directionFiring" or something like that. Inside of love.keypressed, if the key is one of the directions you have, set it to that direction. Then, inside of player.shoot you can say
And do the logic but with a variable instead.
Inside of love.keyReleased, if the key is one of the forum keys, set this variable to nil.

Thank you very much! It's so simple, don't know why I couldn't think of that.

One last thing: Do you know how I could set a cooldown for the shooting?

Sure. Whenever you set player.directionFiring set another variable called player.shootTimer to whatever time you want. Inside of player.update subtract dt from the cooldown. Then inside of love.keypressed check if the cooldown is < 0 in order to fire.

Awesome, thanks.
