Custom commands

The [Command] attribute turns any method or property into a command, and will become available for execution in the command field upon recompilation.

How to create a command

Static example

using UnityEngine;
using Ghostlike.Commands;

public static class NumberCommands
{
    [Command]
    public static int RandomNumber(int from, int to)
    {
        return Random.Range(from, to);
    }
}

The method can be executed immediately by typing: randomnumber 0 10 in the command field.

Non-static example

using UnityEngine;
using Ghostlike.Commands;

public class Player : MonoBehaviour
{
    [SerializeField] private float maxHealth;
    private float currentHealth;

    [Command]
    public int Heal(int amount)
    {
        currentHealth += amount;
        currentHealth = Mathf.Clamp(currentHealth, 0, maxHealth);
    }
}

Contrary to static methods, a non-static method requires an instance in order to be invoked.

Instances are found automatically with Object.FindObjectsByType. This means there is no additional setup required on your part.

Executing the command like this: heal 10 will heal all instances of Player found in the scene. A name can be specified in order to execute the command only on instances with the specified name. It can be specified at the end of the input, prefixed with @. Like so: heal 10 @MyPlayer.
