Hi,
Ok, so I had to go all out on this,
there is a new repository, made with Unity 2019.2 and the whole sample has been reworked to use the latest PlayMaker
https://github.com/jeanfabre/PlayMaker--UnityLearn--2dPlatformer_U2019the package can be
downloaded hereMake sure you work from a fresh projects as it needs special layers,tags and physics 2D settings.
1: install PlayMaker first
2: import the package above
3: the sample is in PlayMaker Unity 2D Demo/Scenes/Playmaker Level
Let me know how it goes,k It's fresh, so their may be odd stuff.
Bye,
Jean
