LEVEL 6

You are almost there! Here is where you would be writing your last pieces of code to finish your smart contract! Hurraaaah on making it so far :)

​

​

​

Let us create 2 entrypoints in this level as well- now we are experts, aren't we :P?

​​

Step 1:

First entrypoint: Our entrypoint from the previous level titled "create_superhero_with_values".

​

Instead of boilerplate code, let me share the actual function code here and explain it to you.

​

public stateful entrypoint create_superhero_with_values(name: string, power:int): int =

let new_avenger : avenger = {

name = name,

power = power}

​

put(state{map_avengers[name] = new_avenger})

put(state{index = (state.index + 1)})

state.index

​

The 2 main takeaway from the above syntax are:

• The value of the state is accessible from inside the contract through an implicitly bound variable state.

• State updates are performed by calling a function put : state => unit

• ​

In the above code, we are updating the value of the index as well as the avenger map to ensure that the information is recorded on the blockchain.

​

Step 2:

We will also create an entrypoint to get the values of our avengers once added. Name it - getSuperhero.

​

Here is the code for the second entrypoint:

public stateful entrypoint getSuperhero(name: string): avenger =

state.map_avengers[name]

​

Once you have put together the entire contract, please copy paste it in an editor for the next step.
