Guard() [6/10]

static bool Debug.Guard ( bool  condition, int  channel, params string[]  messageParts  )

static

If condition is false logs to the Console on the given channel an error message formed by joining the given text strings together and returns true.

If condition is true returns false without logging anything.

This can be useful for checking that the arguments passed to a function are valid and if not returning early with an error.

An error is only logged the first time during a session that the condition evaluates to false to avoid flooding the log file.

In release builds an error will only be logged if the UNITY_ASSERTIONS symbol is defined.

private void CopyComponent(Component component, GameObject to)
{
    if(Debug.Guard(component != null, Channel.Utils, nameof(CopyComponent), " called with null ", nameof(component), " argument.")
        || Debug.Guard(to != null, Channel.Utils, nameof(CopyComponent), " called with null ", nameof(to), " argument."))
    {
        return;
    }
 
    var copy = to.AddComponent(component.GetType());
    var json = JsonUtility.ToJson(component);
    JsonUtility.FromJsonOverwrite(json, copy);
}

Parameters

condition	Condition you expect to be true.
channel	The channel to which the message belongs if logged.
messageParts	strings to join together to form the message.

Returns

true if condition was false; otherwise, false.
