Hello just a genuine question based on the perform with a delay code.
I am creating a scroll shooting game and am wishing to implement new weapon pickups to change how the automatically fired gun from my character functions.
The default function of the gun from the start is;
local function startProjectiles()
local fireTimer
local function fireNow()
if powerUpActive == false then
timer.cancel(fireTimer); fireTimer = nil
else
local bullet = display.newImageRect( “images/projectile_red.png”, 5, 5 )
bullet.x = ship.x -25; bullet.y = ship.y-60; bullet.name = “laser”
physics.addBody( bullet, { isSensor = true } )
audio.play(laserSound)
local bullet = display.newImageRect( “images/projectile_red.png”, 5, 5 )
bullet.x = ship.x +25; bullet.y = ship.y-60; bullet.name = “laser”
physics.addBody( bullet, { isSensor = true } )
weaponGroup:insert( bullet )
end
end
fireTimer = timer.performWithDelay(700, fireNow, 20)
end
startProjectiles()
Variables found at the beginning of the code (if helps);
local background1, background2 --Background moving image
local gameIsActive = true
local powerUpActive = true
local spawnInt = 0 --Gameloop spawn control
local spawnIntMax = 30 --Gameloop max spawn
local spawned = 0 --Keep track of enemies
local spawnedMax = 10 --Max allowed per level
local score = 0
local wave = 1
local enemySpeed = 7 --How fast the enemies are
local scoreText; local levelText; local ship;
local laserSound = audio.loadSound (“sounds/laser.mp3”)
local clickSound = audio.loadSound (“sounds/click.mp3”)
From this code the charecter starts off with 20 shots that are automatically fired from the coordinates indicated.
The main interest of mine is how to access the iteration part of the performWithDelay code. (the 20 found in “(700, fireNow, 20)”).
This would help as I could make ammo pickups available aswell as having the option to display the iteration on screen to help indicate to the user how many bullets they have left to use.
Any help on how to manipulate this part of the code would be ever so grateful and I would appreciate the help highly.
I thank you again,
-Daniel
