[2Col]

Do I have to check if variable's value is different before setting it?

Example

Code:

new bool:IsSpawned[MAX_PLAYERS];

public OnPlayerSpawn(playerid)
{
	IsSpawned[playerid] = true;
	return 1;
}

or

Code:

new bool:IsSpawned[MAX_PLAYERS];

public OnPlayerSpawn(playerid)
{
	if(IsSpawned[playerid] != true)
	{
		IsSpawned[playerid] = true;
	}
	return 1;
}

Which way is better? Or is there no difference?
