Typescript Linting Errors

[freetoplay]

When I use BabylonJS with the TSLinter, I keep getting errors like:

Property 'alpha' does not exist on type 'Camera'.

How do I fix these linting errors?

We would need more info, could you paste your code here or create a playground ?
Also, please check the api to see the public members (https://doc.babylonjs.com/api/classes/babylon.camera)
Happy strict coding   !!

A basic code like this will throw an error in the linter:

scene.activeCamera.alpha += Math.PI;

My tsconfig file looks like this:

{
  "compilerOptions": {
    "target": "es5",
    "module": "esnext",
    "moduleResolution": "node",
    "allowSyntheticDefaultImports": true,
    "sourceMap": true,
    "noImplicitAny": true,
    "removeComments": true,
    "preserveConstEnums": true,
    "baseUrl": ".",
    "lib": ["es2015", "dom"],
    "types": ["node", "jest", "babylonjs"],
    "paths": {
      "@/*": ["src/*"]
    }
  },
  "include": ["src/**/*.ts", "src/**/*.vue", "tests/**/*.ts"],
  "exclude": ["node_modules"]
}

It is  because if you check the api link, again posting here (https://doc.babylonjs.com/api/classes/babylon.camera) there's no public member called as "alpha" and scene.activeCamera returns the base camera class as type. Assuming you are using ArcRotate or ArcFollow camera, refer to this PG -http://playground.babylonjs.com/ts.html#RNXXBZ  you can change the active camera and see.

Just cast:

(<BABYLON.AcrcRotateCamera>)(scene.activeCamera)).alpha += Math.PI;
