SyncSortedSet
SyncSortedSet are sets similar to C# SortedSet<T> that synchronize their contents from the server to the clients.
Unlike SyncHashSets, all elements in a SyncSortedSet are sorted when they are inserted. Please note this has some performance implications.
A SyncSortedSet can contain any supported mirror type
Usage
Add a SyncSortedSet field to your NetworkBehaviour class. For example:
class Player : NetworkBehaviour {
readonly SyncSortedSet<string> skills = new SyncSortedSet<string>();
int skillPoints = 10;
[Command]
public void CmdLearnSkill(string skillName)
{
if (skillPoints > 1)
{
skillPoints--;
skills.Add(skillName);
}
}
}
You can also detect when a SyncSortedSet changes. This is useful for refreshing your character in the client or determining when you need to update your database. Subscribe to the Callback event typically during Start, OnClientStart or OnServerStart for that.
Note that by the time you subscribe, the set will already be initialized, so you will not get a call for the initial data, only updates.
Note SyncSets must be initialized in the constructor, not in Startxxx(). You can make them readonly to ensure correct usage.
class Player : NetworkBehaviour
{
readonly SyncSortedSet<string> buffs = new SyncSortedSet<string>();
// this will add the delegate on the client.
// Use OnStartServer instead if you want it on the server
public override void OnStartClient()
{
buffs.Callback += OnBuffsChanged;
}
void OnBuffsChanged(SyncSortedSet<string>.Operation op, string buff)
{
switch (op)
{
case SyncSortedSet<string>.Operation.OP_ADD:
// we added a buff, draw an icon on the character
break;
case SyncSortedSet<string>.Operation.OP_CLEAR:
// clear all buffs from the character
break;
case SyncSortedSet<string>.Operation.OP_REMOVE:
// We removed a buff from the character
break;
}
}
}
