Visual Scripting
Programming, like algebra, works with abstract concepts. For example, instead of using fixed numbers, we can write equations like X + Y = Z, which lets us change values without rewriting the entire equation. This abstraction is especially useful in game development, where we often need to calculate things like a player's score or health on the fly, even when we don’t know the exact values yet.
Since abstraction can be tricky to grasp, it’s helpful to visualize how things interact. In game design, we often start by mapping out game loops in flowcharts before development begins.
Visual scripting offers a way to visualize programming by using a node-based interface to represent and connect game logic. It’s an excellent way for beginners to learn basic programming flow and quickly develop without needing to write code.
In This Section:​
In this section, we will cover the following topics:
1. Script Graphs​
Script Graphs allow the creation of logic-based interactions using a node-based interface. These graphs serve as the foundation for building game mechanics and logic without traditional coding.
2. State Graphs​
State Graphs provide a structured approach to controlling object behaviors, game states, and complex interactions. These graphs are particularly useful for organizing self-contained behaviors, such as animations, transitions, and state changes.
3. Park Clean-Up​
A hands-on game development project that walks through the process of implementing visual scripting techniques. This project will focus on building a fully interactive game experience by applying the tools and concepts covered throughout the section.
