If there are errors in the project imported scripts will not compile until the errors are fixed.

We highly recommend using Source Control with Unity Projects. Taking a little time to setup this up first can save you countless hours in the long run!


  • Playmaker works with Unity 2017.4 and higher.
  • System requirements are the same as for Unity.
  • Alpha and beta versions of Unity are not officially supported.


PlayMaker Versions

There are versions of PlayMaker uploaded for 2017.4, 2018.3 and 2019.3 for maximum compatibility across all Unity versions. The 2019.3 version can be used with Unity 2019.3 and higher.

Normally the Asset Store will automatically give you the correct version, but it can get confused when you switch between versions of Unity.

Follow this guide if you're switching Unity versions and get the wrong version of PlayMaker (e.g., you have errors with a fresh install).


Updating Unity

NOTE: Alpha and beta versions of Unity are not officially supported, but we do try to fix any issues so you can use PlayMaker with the latest beta. Alpha versions of Unity are likely to break often. Alpha versions end in .aXX, beta versions end in .bXX, official releases end in .fXX.

When you update Unity you may also need to update PlayMaker.

There are versions of PlayMaker uploaded for Unity 2017.4, 2018.3, and 2019.3 that cover compatibility across all Unity versions.

So for example:

  • If you updated from 2017.4 to 2018.1 you don't need to update PlayMaker, since they use the same version of PlayMaker.
  • If you updated from 2018.1 to 2018.3 you will need to update PlayMaker since it requires a new version of PlayMaker.

Use the Asset Store or the Hutong Games Store download zip to update PlayMaker.
