Sprite animation loops constantly? Need it to stop!

@Martin yeah i need to start doing this delete sprite its just taking the plunge

Just a side note

The following code "should" do exactly the same and not use a sprite slot

// Do whatever you need to do
// In your loop you can now say
for n = 0 to len(enemies) loop
    if enemies[n] != false then
        // do all your stuff, including when you're done with it...
        removeSprite(enemies[n])
        enemies[n] = false
    endif
repeat

I just realised why this doesn't work and I am going to try to get it addressed in a future patch as to me it is very odd behaviour and 100% cannot be "by design"

You cannot compare a sprite object to anything other than another sprite object, so setting it to false , null, void, 1, "nothing" or anything else will not work... hence the requirement for an empty sprite

Thanks for all the replies, I'll check them out today!

Just had a thought laying here after just waking up, and that is;

// Do whatever you need to do
// In your loop you can now say
for n = 0 to len(enemies) loop
if enemies[n].sprite != visible then
If explosionSprite[n] frame count>60
removeSprite(enemies[n])
Endif
endif
repeat

As only destroyed aliens will ever be exploding?...

Anyways, thaanjs again. Will update how it's gone :)

the above worked fine by the way, thanks for all the pointers @Martin and @MikeDX

spikey

@SwitchedOn sorry I did not look up the docs, but what is the variable visible? Is this pseudo code?

As soon as i hit an enemy, i put it outside the screen area and make it static.

sprite.y = -10000// shoud be enough to avoid any collision with other sprites
setSpriteSpeed( sprite, {0.0} ) // i don't want the enemy to come back in the screen

I don't delete the sprite,

Yea it is, but its a 'get'

getSpriteVisibility(spriteName)

Can also use a 'set'

setSpriteVisibility(sprintName, Boolean)

Whilst this works, I wouldn't approve of this as a best practice way of doing things.

Yep, could end up being a bit of a memory hog - plus as they are still active to a degree, could cause issues in detections etc.

In practice, in a space invader/galaxian game, i have a constant number of enemies (50 max).
I recycle the sprites on the next stage, only by changing properties.(ecolo coding)
Since the sprites are static and far away, they don't collide with bullets, Ships etc.
I do the same with bullets, explosions.
I admit it's a rough method, but it works well.
Give me stack and list, and i'll make it better.
