error cs0116 and cs0115

i know getting an answer is slim, but here we go.
ml-agent release 18, trying to make Learning-Environment-Create-New.md (rollerball)
install both com.agent package following every step carefully
get a nice youtube tutorial

Unity3D+ML-Agents Creating a Scene and Training an Agent Basics (RollerBall Tutorial)

got an error at the script

these 3 lines (CollectObservations, forceMultiplier, OnActionReceived)
public override void CollectObservations(VectorSensor sensor)
public float forceMultiplier = 10;
public override void OnActionReceived(ActionBuffers actionBuffers)

im stupid person need answer, i dont have anything to offer you, maybe a prayer for your well being is enough to get an answer?

here the code, its copy paste from ml-agents/docs/Learning-Environment-Create-New.md at main · Unity-Technologies/ml-agents · GitHub
its same script, 99% similar with that youtube tutorial.

someone really need to update those ml-agent tutorial,
i just copy paste ready-made code and still got an error. that funny…

my suspicion is these 2 package have different line of code when called (either because it installed locally or the code changed so much)

that why it said 0 reference

while other said

i really want to use release 1 ml-agent like those youtube tutorial
but im sure 100% this package is not there anymore

even using release 1 i think it will be same problem. god please help this lost soul.
