Language server thinks Actor does not have stop() property

[lincore81]

Hey y'all, I can't make up my mind if the type definitions are lacking or if it's me, although I suspect it to be the latter.

I'm following the flappy bird tutorial (chapter 5), which includes stopping the bird on collision. And while the method definitely works, the language server thinks it doesn't exist.

I encountered the issue in neovim and vscode (default tsconfig except target set to esnext). Does anybody know what's going on here?

package.json:

--- snip ---
  "devDependencies": {
    "typescript": "^5.7.2",
    "vite": "^6.0.6"
  },
  "dependencies": {
    "excalibur": "^0.30.2"
  }

src/actors/bird/bird.ts:

import { Actor, clamp, Collider, Color, Engine, Keys, vec } from "excalibur";
import { Ground } from "../ground/ground";
import { Pipe } from "../pipe/pipe";

export class Bird extends Actor {
  jumping = false;

  constructor() {
    super({
      pos: vec(100, 120),
      width: 16,
      height: 16,
      color: Color.Yellow,
    });
  }
  
  // --- SNIP ---

  override onCollisionStart(_: Collider, other: Collider): void {
    if (other.owner instanceof Ground || other.owner instanceof Pipe) {
      this.stop(); // <-- lsp error: Property 'stop' does not exist on type 'Bird'.
    }
  }
}

@lincore81 Thanks for the post! Apologies for this, this is a gap in the tutorial text! I'll update the prose to fix this asap.

.stop() is implemented on the Bird type

Give the final code a look to cross check any errors/gaps you find

@lincore81 I added some more clarification to the docs! f0d9a6b
