TSMPNetworkBehaviour

Namespace: K13A.TSMP.Udon

Base type for TSMP-synchronized behaviours.

Use this when a component should participate in TSMP message routing. It provides a network ID, receive interpolation policy, lifecycle hooks, and SendTransRPC.

Fields

Field	Type	Use
networkId	ushort	Routes payload messages to this behaviour.
sendMode	SendMode	Component-wide override of automatic fields' change filtering. Defaults to Default.
receiveInterpolation	ReceiveInterpolationMode	Controls receive behaviour.
continuousInterpolationRate	float	Smoothing rate for continuous receive mode.
transRpcEncoder	TSMPEncoder	Encoder used by SendTransRPC. Assigned by setup.
lastVariableHash	uint	Last received variable hash.
lastRpcHash	uint	Last received RPC hash.
lastRpcNetworkId	ushort	Network ID for the last received RPC.
lastRpcArgumentCount	int	Argument count for the last received RPC.
lastRpcMethodName	string	Method name for the last received RPC.

Do not assign transRpcEncoder manually in normal scenes. Let TSMPSetup assign it.

SendMode

Namespace: K13A.TSMP.Udon. Inspector label: Send Mode.

Value	Numeric value	Effective SendOnChange
Default	0	Each field's attribute setting.
OnChange	1	true for every automatic field on this component.
Always	2	false for every automatic field on this component.

sendMode = SendMode.Always;

Changes are read during encoding, without rebuilding bindings. The existing field snapshots and successful-output times remain intact, so switching modes does not bypass MinSendInterval. Unknown enum values fall back to Default. Existing scenes and prefabs without this field use Default.

This override does not modify attribute metadata, priority, direction, capture logic, RPC behavior or manual Writer calls. OnChange retains the Encoder's periodic refresh. Always remains subject to minimum intervals and payload capacity. See Send Mode for usage examples.

ReceiveInterpolationMode

Value	Meaning
None	Ignore received values.
Discrete	Apply received values directly.
Continuous	Store targets and interpolate where supported.

Built-in components decide how to use Continuous. Custom components should check receiveInterpolation before applying received data.

Lifecycle methods

Method	Called when
TSMPBeforeEncode()	Before encoder reads [TransSync] fields.
OnTSMPVariableReceived()	After decoder applies a synchronized field.
OnTSMPVariableChanged(uint variableHash)	From the base receive handler.
OnTSMPRpcReceived()	After decoder dispatches a TSMP RPC.
OnTSMPRpc(uint rpcHash)	From the base RPC receive handler.

Typical custom component flow:

public override void TSMPBeforeEncode()
{
    packedBytes = BuildPacket();
}

public override void OnTSMPVariableReceived()
{
    if (receiveInterpolation == ReceiveInterpolationMode.None)
        return;

    ApplyPacket(packedBytes);
    OnTSMPVariableChanged(lastVariableHash);
}

Utility methods

Method	Use
IsTSMPActive()	Returns enabled and active-in-hierarchy state.
GetReceiveInterpolationStep()	Returns a clamped 0..1 interpolation step.
SendTransRPC(string methodName, RPCTarget target)	Queue an RPC event through TSMP.

RPCTarget

Value	Behaviour
Local	Execute locally only.
Remote	Queue for receivers only.
All	Execute locally and queue for receivers.

SendTransRPC hashes the method name and queues it through the assigned encoder. The receiving side dispatches by method name after decode.

Example RPC

public override void Interact()
{
    SendTransRPC(nameof(ToggleObject), RPCTarget.All);
}

public void ToggleObject()
{
    target.SetActive(!target.activeSelf);
}
