![]() I typically use Editra v0.7.12 to write Python code, when including the psyco try/except block, Editra would occasionally crash. If there’s information that I have glossed over or skipped entirely, let me know, and I will add it in, with future edits of the tutorials. If there are any comments about the tutorials, whether they are critical or complimentary, you’re welcome to post them. If you have already coded the first tutorial you should do just fine with this one. There are some very good resources available for Python, either through THE OFFICIAL PYTHON WEB-SITE or by completing a Google search on the Python version you have installed. If that is not the case, then you should, at the very least, want to have the Python documentation(included in the Python install) at hand incase you wanted it for a reference. One important point about these tutorials is the assumption that anyone following along already has at least a basic knowledge of how Python code is structured. The next step, will be building on that example, we will create a star field background, then write the code to animate it. In the first tutorial, we created a simple window using Python and Pygame. Step 3: Draw the object in isolation with the forces that act on itįinally, draw the object on its own (omitting external elements like other objects, the floor, the ceiling, etc.) and the forces that are acting on it. Tags: Editra, Python 3.x, Pygame, programming, star-field simulation Therefore, we come to the conclusion that 4 forces are acting on our block: Returning to our example: the block is pushed, so a pushing force acts on the block there is friction between the block and the floor, so a friction force acts on the block (opposing its motion) the block is subject to the force of gravity the floor exerts the normal force on the block in order to prevent the penetration of the block. Step 2: Determine the forces that act on the objectĬarefully observe your sketch, and think about all the forces that are acting on the object. This sketch will help you determine what forces act on the object. A sketch of the block pushed over the floor Push Friction ![]()
