I noticed at 4:50 that the Piston Rigid Body Constraint was already set. However in the previous minutes the constraint wasn't shown. I went back twice to redo in case i missed it. This kind of was the point of the video. To see how to set it up and how it works. Please add it back in, so we can see what you did.
Hi Rahim,
What's missing, is mainly just clicking the Rigid Body Constraint Button to Add the Constraint, and set it to Piston. As mentioned, the Constraint is very similar to the Slider Constraint, so maybe re-watch that Lesson.
Let us know if you still can't get it to work (telling us what you tried, exactly).
Thank you for replying to me. I do appreciate it. And since you have done this so many times. I am sure that it might seem easy for you, almost second nature. However as a learner, it can be confusing when you realize that you aren't obtaining the same result, and it takes time to review where the differences are. Being the main point of the video, to see it demonstrated. It would help the learning process to actually see it demonstrated.
