Examples

Using Oloo.assign

const { setup } = require('@learngamedevelopment/oloo');
setup();

const Object1 = {
  create() {
    const object1 = Object.create(Object1);

    object1.var = 0;
    object1.var2 = 'hi';

    return object1;
  },

  virtualMethod() {
    console.log('Base Class!');
  }
}

const Object2 = {
  create() {
    const object2 = Oloo.assign(Object1.create(), Object2);
    return object2;
  },

  virtualMethod() {
    Oloo.base(this, this.virtualMethod);
    console.log('Inherited Class!');
  }
}

const object2Instance = Object2.create();
object2Instance.virtualMethod();
// Base Class!
// Inherited Class!

Using Oloo.assignSlow + Oloo.createSlow

const { setup } = require('@learngamedevelopment/oloo');
setup();

const Object1 = {
  create() {
    // must use createSlow in the first object of the chain.
    const object1 = Object.createSlow(Object1);

    object1.var = 0;
    object1.var2 = 'hi';

    return object1;
  },

  virtualMethod() {
    console.log('Base Class!');
  }
}

const Object2 = {
  create() {
    const object2 = Oloo.assignSlow(Object1.create(), Object2);
    return object2;
  },

  virtualMethod() {
    Oloo.base(this, this.virtualMethod);
    console.log('Inherited Class!');
  }
}

const object2Instance = Object2.create();
object2Instance.virtualMethod();
// Base Class!
// Inherited Class!

Release Notes

2.2.0+

• Got rid of parent field on objects, we keep track of the parent throughout the life of the method call and then remove it.
  • In the past we use to inject parent into objects to know if we already called a method on the parent. Now we don't.
• Improved error handling.

2.1.0+

• Improved speed tremendously. Kept older assign as assignSlow for creating classes that don't get created often.
• Added debugging capabilities.
  • If you add a displayName to your Obj we will make sure it appears in the Stack Trace.
  • Check to make sure displayName is a function name. Also consider compiling out displayName with Babel.
