LEVEL 5

We are nearing completion now! Wohoo, how exciting!

​

​

​

Let us create 2 entrypoints in this level - because, why not :D!

​​

Step 1:

First entrypoint: A function named create_random_power - which would create a random power for the superhero and allocate it.

​

How can we do this?

We will use a variable from the Chain library - known as Chain.timestamp. This will return the timestamp of the current block. We will add this with the index variable defined in our record "state".

​

Why are we doing this?

This will help you learn more about the parameters assocated with the Chain.

​​

Step 2:

Step a:

Second entrypoint: create_superhero

This will take in a parameter "name" of type "string" and return nothing.

​

What should this entrypoint do?

1. This should check if the name satisfies the name check by passing it to the name_check function. For this, we will use the keyword - require.

​

What does the require function do?

​

It is used to add constraint to a function. If the require statement is not satisfied, the function execution will not proceed further.

​

Example boilerplate code:

require(function(argument), "Message that you would like to print")

​

Step b:

Create a variable power and call the function "create_random_power" with the name as the argument and assign the return value to this variable.

​

Example boilerplate code:

let var_name : data_type = create_random_power(name)

​

Step c:

 Now you need to call another function "create_superhero_with_values" with the name and the power as the parameters. This is the function that will create the superhero for us. We will write this function in the next level.

​

Let us create these two entrypoints and move forward!
