I’m currently making a fun plane game for school, the coding is messy as it is my first time doing this. I am currently confused on why missiles (the little things that follow your y axis) stop tracking targets after another missile spawns. If anyone can help, thank you!

Looking at your code @2cool4u The problem is that **every enemy missile shares the same global variable** (`ENEMY_MISSILE`), so whenever a new missile is spawned, `ENEMY_MISSILE` is reassigned to the newest sprite. After that, all of your `forever` loops are only updating that newest missile, and the older missiles are abandoned

Specifically:

```typescript
ENEMY_MISSILE = sprites.create(...)

```

creates a new missile, but overwrites the old reference.

Then later:

```typescript
forever(function () {
    ENEMY_MISSILE.y = tracked_target_pathfind
})

```

only affects whatever missile was created most recently.

A much better approach is to update **all** tracking missiles:

```typescript
forever(function () {
    for (let missile of sprites.allOfKind(SpriteKind.tracking_missile)) {
        missile.y = tracked_target_pathfind
    }
})

```

or even better, give each missile its own tracking logic when it’s created instead of relying on one global variable.

I also noticed a couple of other things:

- The `for (let index = 0; index < 1; index++)` loops don’t do anything useful—you can just remove them and create the sprite directly.
- This loop is suspicious:

```typescript
for (let ENEMY_MISSILE2 of sprites.allOfKind(SpriteKind.tracking_missile)) {
    ENEMY_MISSILE2 = sprites.createProjectileFromSprite(...)
}

```

Assigning to `ENEMY_MISSILE2` doesn’t replace the sprite in the array—it just changes the local variable, so it probably isn’t doing what you expect.

So the issue isn’t really that you’re recreating sprites in `game.onUpdate` (you’re actually spawning them every 5 seconds). It’s mainly that you’re storing every missile in the same variable, causing only the newest missile to continue tracking.

If you’re using Blocks, you could either:

- update **all** tracking missiles in a loop (`sprites.allOfKind(...)`) instead of just `ENEMY_MISSILE`, or
- if you’re comfortable switching to JavaScript for a small part, replace the code that updates `ENEMY_MISSILE.y` with:

```typescript
for (let missile of sprites.allOfKind(SpriteKind.tracking_missile)) {
    missile.y = tracked_target_pathfind
}

```

I’m on mobile u can move but the background doesn’t move so it doesn’t seem like it to prove my point move forwards while shooting with a the projectiles can’t keep up but if you just shoot they got forwards

Thank you so much! I’ve done some work and figured out of fixes. Is there anything else i can do to better optimize code?

try the missiles, they are transferred less momentum, so it’d be more obvious

Is actually pretty good I needed to make better path finding for the ai to fight each other too
