Creating Custom Nodes

MathsEngine is designed to be extensible.
You can create your own mathematical operations by implementing custom Math Nodes.

All nodes derive from BaseMathNode.

Creating a Custom Node

To create a new node:

1. Create a class that inherits from BaseMathNode
2. Define the node inputs
3. Implement the Calculate() function
4. Implement ToEquation() for debugging and visualization

---

Example: Square Node

The following example creates a node that squares a value.

result = value * value

using Baruah.MathsEngine.Core;
using UnityEngine;
 
public class SquareNode : BaseMathNode
{
    [SerializeField]
    private BaseMathNode value;
 
    public override float Calculate(object[] parameters)
    {
        float v = value.Calculate(parameters);
        return v * v;
    }
 
    public override string ToEquation()
    {
        return $"({value.ToEquation()}^2)";
    }
}

Node Inputs

Nodes usually take other nodes as inputs.

Example:

Multiply
├─ Node A
└─ Node B

Implementation example:

[SerializeField]
private BaseMathNode inputA;
 
[SerializeField]
private BaseMathNode inputB;

---

Using the Custom Node

Once created, the node can be added to a MathFormula.

Example graph:

Square
└─ Constant(5)

Result:

5² = 25
