AnAl question for enemies

Post by GungnirDev »

I want to make an enemy type glow and have designed a simple animation for this using ANimations And Love (AnAl). Problem being that I could not simply assign this IMG to all enemies, so I assigned them all a dummy "null" image and drew the animation at enemy.x, enemy.y provided enemy.img == null. This technically worked, however, I now get a bug wherein the animation sometimes disappears halfway down the screen. It happens about half the time; the other half of the time it works great. Suggestions?

Here is the foe.lua code (the full game is too big, but I'm fairly certain the problem is in foe.lua)

Code: Select all

 foe = {}
	
	bullets = {}
	
function trigger()	
	spawn = math.random(1,5)
	end
	
function brigger()
	spawnboss = math.random(1,6)
end

function myswerve()
	swerve = math.random(5)
end
	
dofire = 0
	
function firing()
	dofire = 1
end

	bosshealth = 100

function foe.load()

cron.every (1, trigger)

cron.every (3, brigger)

cron.every (4, myswerve)

cron.every (3, firing)

	swerve = 3
	
	spawn = 0
	
	spawnboss = 0
	
	respawn = 0
	
	reinforce = 0

I would love to help, but I've never used Anal before. I suggest you try printing out debugging info though and trying to pinpoint the problem if you haven't already. Also, I suspect a lot of the love community is busy with Christmas holidays so you likely won't get a better answer until after the 25th-ish.

Sorry I couldn't be more help. :3

No, that's OK.

Printing debugging info is one thing but the problem is that it doesn't appear to be a bug. I'm not getting any sort of error message; it's all in working order except that the enemy disappears halfway down the screen.
