Flyweight

Flyweight Dp is used when we have one of the following situations:

• Memory constrain;
• Generation of many identical objects with little difference;

The Flyweight dp is described with two states:

1. Intrinsic State - this is the state which is shared with multiple object;
2. Extrinsic State - this state can varies in different object contexts and cannot be shared

---

so to be much more clear the differences between those two states let me give you an example: let's have game in which the hero should collect coins which have different values,so in the table below I've splited the object inthe needed states:

Interinsic	Extrinsic
coin form	coin value
coin fall speed	coin back pic
