Eval expression
The Eval expression node is the "Swiss Army Knife" of mathematics in ERGS. Instead of stringing together dozens of simple math nodes, you can write a complex formula directly into the expression property using variables A through F.
When to use this node:
* Complex Scoring Formulas: Calculating a final game grade based on multiple variables, such as: (A * 100) + (B * 50) - (C * 10) where A is items, B is puzzles, and C is hints used.
* Coordinate Transformations: Calculating the target position for a 2D or 3D prop using trigonometric or geometric formulas.
* Bitwise Logic: Performing advanced bitwise AND (&) or OR (|) operations on raw hardware data streams.
Pro Tip:
Use this node to keep your diagrams clean. If you find yourself using more than three simple math nodes in a row, an Eval node is likely a more readable and maintainable choice.
