Improve ability documentation #244

Zarel · 2018-10-15T00:33:46Z

The warrior object isn't actually documented outside of the auto-generated README, so the auto-generated README could stand to be a bit more specific than it currently is.

Abilities now document arguments, and contain some other relevant information previously only found in tips.

Hello @Zarel, just wanted to thank you for your contribution, and let you know that it didn't go by unnoticed. I'll be a bit busy for a couple more days, and then I'll review this.

Zarel · 2018-11-09T15:32:48Z

Heya, just poking to make sure you didn't forget.

Hey, sorry again for the delay. This is going to be a great addition, thanks! I made some comments/suggestions.

packages/warriorjs-abilities/src/attack.js

  return unit => ({
    action: true,
-    description: `Attacks a unit in the given direction (\`'${defaultDirection}'\` by default), dealing ${power} HP of damage.`,
+    argumentsDescription: `direction = '${defaultDirection}'`,


I'd rename argumentsDescription to params and include the name and type of the parameter, in addition to the description, in a more machine-friendly format. Then, when presenting the info to the user, we can choose what to display and in which format. Concretely, I suggest the following:

Suggested change

argumentsDescription: `direction = '${defaultDirection}'`,

params: [{

name: 'direction',

type: 'string',

description: 'The direction.',

defaultValue: `'${defaultDirection}'`,

}],

For the IntelliSense on warriorjs.com, I'm inferring those values from the description of the ability. This will allow me to remove that fragile code.

I like the addition you did! I find the wording unnecessarily long though. What about:

Suggested change

description: `Attacks a unit in the given direction (${defaultDirection} by default), dealing ${power} HP of damage in any direction except backward (reduced to ${backwardPower} if attacking backward).`,

description: `Attacks a unit in the given direction (${defaultDirection} by default), dealing ${power} HP of damage (${backwardPower} HP if attacking backward).`,

This is missing the params, and for Senses (which always return something), we could add a returns:

I think we don't need to clarify the rounding mode (it's what most people would expect).

Suggested change

'Gains 10% of max health back (rounded half-up to the nearest integer), but does nothing more.',

We need to update this to use the new params (let's not show the type information here, just parameter name and default value if it exists). Examples:

warrior.directionOf(space)

warrior.walk(direction = 'forward')
