【Unity Tutorial】Creating a game using Playmaker① From basic introduction to installing

I will introduce the basic functions and how to use ‘PlayMaker’, and explain how to create an easy game with Unity in this article series.

In this article, I will introduce the basics of PlayMaker, and how to install it.

You cannot use scripts with STYLY, but you can use PlayMaker to create a similar function.

One strength of PlayMaker is that the user does not need programming experience with C# in order to create Unity VR content.

Also, by combining PlayMaker with STYLY, users can create whatever they want with VR.

After you read my article, I hope you try and create your very own VR content.

PlayMaker Basics

PlayMaker Strengths

  • State transition base flows
  • No need for coding to create logics
  • Visualized program states, which help debugging
  • Easy combining with existing code and other assets
  • Users can create original ‘actions’
  • Only PlayMaker is needed
  • You can combine PlayMaker with C# scripts, and choose which parts you want PlayMaker to be applied

What you can obtain with PlayMaker

  • Mock production/Rapid prototyping
  • UI/State transition management system
  • Tween animation control
  • AI thinking routine
  • Unity Engine API knowledge

    Cautions for team development

  • No code means no merging (But you can use the Template Export function for some use)
  • Strict capsuling is hard to achieve
  • PlayMaker has lots of flexibility, and users can freely create any kind of logic, so it may be hard to create a sense of unity

    Countermeasures

  • Limiting use to specific scenes
  • Using only with existing code and for specific scenes
  • Use all codes as PlayMaker actions
  • Limit use to managing state transition status
  • Limit use to managing iTween

What is a FSM

PlayMaker uses UMLs called FSM(Finite State Machine) to describe state transition status.

Main Components

  • State:Status of Object
  • Event:Trigger for a state transtion
  • Action:Action that occurs at a specific status
  • Variable:Object values used by FSMs are stored

Example:Player Character

  • State:’Standing’, ‘Walking’, ‘Running’, ‘Jumping’, etc…
  • Event:State transition from ‘Standing’ to ‘Walking’, ‘Walking’ to ‘Running’, etc…
  • Action:What the character does when ‘Standing’, ‘Walking’, etc…
  • Variable:The moving direction of the Player (Vector3), the speed (float), etc…
