### Setting Allowed Signal Modes for a Flow Node

Source: https://github.com/mothcocoon/flowgraph/blob/5.x/docs/Features/SignalModes.md

Defines the signal modes that are permitted for a specific Flow Node class. This example shows how to restrict a node to only Enabled and Disabled modes.

```cpp
AllowedSignalModes = {EFlowSignalMode::Enabled, EFlowSignalMode::Disabled};
```

--------------------------------

### Get Dynamic Node Title Color

Source: https://github.com/mothcocoon/flowgraph/blob/5.x/docs/Releases/Version11.md

Implement GetDynamicTitleColor() in UFlowNode to allow runtime-based color changes for node instances.

```cpp
FLinearColor UMyFlowNode::GetDynamicTitleColor() const {
  // Return color based on runtime logic
  return FLinearColor::Green;
}
```

--------------------------------

### Configure Node Spawn Shortcuts

Source: https://github.com/mothcocoon/flowgraph/blob/5.x/docs/Guides/AddingNodeSpawnShortcut.md

Add this section to your project's `DefaultEditorPerProjectUserSettings.ini` file to define keyboard shortcuts for spawning various Flow Graph nodes. Restart the editor after making changes to apply them.

```ini
[FlowSpawnNodes]
; Flow
+Node=(Class=FlowNode_OnNotifyFromActor Key=A Shift=false Ctrl=false Alt=false)
+Node=(Class=FlowNode_Finish Key=F Shift=false Ctrl=false Alt=false)
+Node=(Class=FlowNode_SubGraph Key=G Shift=false Ctrl=false Alt=false)
+Node=(Class=FlowNode_CustomInput Key=I Shift=false Ctrl=false Alt=false)
+Node=(Class=FlowNode_Log Key=L Shift=false Ctrl=false Alt=false)
+Node=(Class=FlowNode_ExecutionMultiGate Key=M Shift=false Ctrl=false Alt=false)
+Node=(Class=FlowNode_NotifyActor Key=N Shift=false Ctrl=false Alt=false)
+Node=(Class=FlowNode_CustomOutput Key=O Shift=false Ctrl=false Alt=false)
+Node=(Class=FlowNode_Reroute Key=R Shift=false Ctrl=false Alt=false)
+Node=(Class=FlowNode_ExecutionSequence Key=S Shift=false Ctrl=false Alt=false)
+Node=(Class=FlowNode_Timer Key=T Shift=false Ctrl=false Alt=false)
; Comment
+Node=(Name=Comment Key=C Shift=false Ctrl=false Alt=false)
```

--------------------------------

### Initialize Flow Node Instance

Source: https://github.com/mothcocoon/flowgraph/blob/5.x/docs/Releases/Version11.md

Call InitializeInstance() on a Flow Node just after its creation during Flow Asset initialization, before graph execution.

```cpp
FlowNode->InitializeInstance();
```

--------------------------------

### Trigger Output with String/Text/TCHAR*

Source: https://github.com/mothcocoon/flowgraph/blob/5.x/docs/Releases/Version11.md

Use the new C++ flavors of TriggerOutput() methods to pass FString, FText, or TCHAR* data.

```cpp
TriggerOutput(TEXT("MyString"));
TriggerOutput(FText::FromString("MyText"));
TriggerOutput(TEXT('c'));
```

--------------------------------

### Set Numbered Input/Output Pins

Source: https://github.com/mothcocoon/flowgraph/blob/5.x/docs/Releases/Version11.md

Use SetNumberedInputPins() and SetNumberedOutputPins() for adding numbered pins in C++.

```cpp
SetNumberedInputPins(3);
SetNumberedOutputPins(2);
```

--------------------------------

### Disable Flow Subsystem on Clients

Source: https://github.com/mothcocoon/flowgraph/blob/5.x/docs/Releases/Version11.md

Set bCreateFlowSubsystemOnClients to false in Flow Settings to disable the Flow Subsystem on client machines.

```cpp
UFlowSettings* Settings = GetMutableDefault<UFlowSettings>();
Settings->bCreateFlowSubsystemOnClients = false;
```

--------------------------------

### Enable Flow Plugin in .uproject File

Source: https://github.com/mothcocoon/flowgraph/blob/5.x/docs/Releases/Version22.md

To re-enable the Flow plugin in your project, add this section to the Plugins list in your .uproject file. This is necessary as the plugin is now disabled by default.

```json
{
    "Name": "Flow",
    "Enabled": true
}
```

--------------------------------

### Change Root Flow Mode

Source: https://github.com/mothcocoon/flowgraph/blob/5.x/docs/Releases/Version11.md

Select a different RootFlowMode on the Flow Component in World Settings to control Flow asset instantiation on clients.

```cpp
// In World Settings -> Flow Component -> Root Flow Mode
// Select 'Client' or 'ServerOnly' as needed.
```

--------------------------------

### Define C++ Flow Node Pins

Source: https://github.com/mothcocoon/flowgraph/blob/5.x/docs/Releases/Version11.md

Update C++ Flow Node pins by defining them using methods like AddInputPins or by constructing FFlowPin structs with tooltips.

```cpp
InputPins.Add(FFlowPin(TEXT("Spawn"), TEXT("MyTooltip")));
InputPins.Add(FFlowPin(TEXT("Despawn")));
```

--------------------------------

### Log Error Message Permanently

Source: https://github.com/mothcocoon/flowgraph/blob/5.x/docs/Releases/Version11.md

Log error messages permanently on screen using UFlowNode::LogError with OnScreenMessageType::Permanent. Use Temporary to revert to old behavior.

```cpp
LogError(TEXT("This is a permanent error message."), OnScreenMessageType::Permanent);
LogError(TEXT("This is a temporary error message."), OnScreenMessageType::Temporary);
```

--------------------------------

### Add Flow Graph Plugin as Git Submodule

Source: https://github.com/mothcocoon/flowgraph/blob/5.x/docs/Overview/GettingStarted.md

Include the Flow Graph plugin repository as a dependency in your project using Git submodules. Ensure you specify the correct branch (e.g., '5.0').

```bash
git submodule add -b 5.0 https://github.com/MothCocoon/FlowGraph.git Plugins/Flow
```

--------------------------------

### Limit Allowed Node Classes in Flow Asset

Source: https://github.com/mothcocoon/flowgraph/blob/5.x/docs/Releases/Version11.md

Use the AllowedNodeClasses array in UFlowAsset to restrict which node types can be added to a specific Flow Asset.

```cpp
AllowedNodeClasses.Add(UMyDialogueNode::StaticClass());
```

--------------------------------

### Add/Remove Identity Tags

Source: https://github.com/mothcocoon/flowgraph/blob/5.x/docs/Releases/Version11.md

Manage Identity Tags on a Flow Component during gameplay using AddIdentityTag() and RemoveIdentityTag().

```cpp
FlowComponent->AddIdentityTag(TEXT("Player"));
FlowComponent->RemoveIdentityTag(TEXT("NPC"));
```

--------------------------------

### Check Flow Node Data Validity

Source: https://github.com/mothcocoon/flowgraph/blob/5.x/docs/Releases/Version11.md

Implement IsDataValid() in UFlowAsset to return the validation result of Flow Nodes.

```cpp
if (FlowAsset->IsDataValid()) {
  // Flow data is valid
}
```

--------------------------------

### Override Node-Specific Colors

Source: https://github.com/mothcocoon/flowgraph/blob/5.x/docs/Releases/Version11.md

Set NodeSpecificColors in UFlowGraphSettings to customize the color of any node.

```cpp
UFlowGraphSettings* Settings = GetMutableDefault<UFlowGraphSettings>();
Settings->NodeSpecificColors.Add(UFlowNode::StaticClass(), FLinearColor::Red);
```

--------------------------------

### Hide Nodes from Flow Palette

Source: https://github.com/mothcocoon/flowgraph/blob/5.x/docs/Releases/Version11.md

Add node classes to NodesHiddenFromPalette in UFlowGraphSettings to hide them from the Flow Palette without code changes.

```cpp
UFlowGraphSettings* Settings = GetMutableDefault<UFlowGraphSettings>();
Settings->NodesHiddenFromPalette.Add(UMyCustomNode::StaticClass());
```
