Preprocessor

The Preprocessor node give instruction to the compiler to preprocess the information before actual compilation starts. This node can be used to run specific logic based on platform, see https://docs.unity3d.com/Manual/PlatformDependentCompilation.html

Caution

This node doesn't work when running with reflection mode.

Examples

Graph:

Generated script:

#pragma warning disable
using UnityEngine;
using System.Collections.Generic;

namespace MaxyGames.Generated {
	public class new_graph : MaxyGames.RuntimeBehaviour {

		void Start() {
			#if UNITY_ANDROID
			Debug.Log("Run on Android");
			#elif UNITY_IPHONE
			Debug.Log("Run on IPhone");
			#endif
		}
	}
}

Output on running with Android platform:

Run on Android

Output on running with IPhone platform:

Run on IPhone

Note

If the graph is run within in the Unity Editor it will have no output because Unity Editor is not a Android or IPhone platform, use UNITY_EDITOR if you want to run it within the Editor.
