Pulley

General

The wikipedia definition of a pulley is:
"a wheel on an axle or shaft that is designed to support movement and change of direction of a taut cable or belt, or transfer of power between the shaft and cable or belt"
The pulleys we will be generating are generally simpler setups. They mostly consist of a rope with a physics object (rigid body) on each end. This is because of how the system is used to create the pulleys. Ropes cannot be intertwined between objects accurately, so they are just generated above their setup locations and allowed to fall into position. As a final note, the pulley can also be tied into demonstrating the wheel and axle simple machine as well.

Varieties

Hook on an end to latch onto other objects

This focuses on the pulley's inherent nature of changing the direction of force. The hooks allow the player to attach one end to various objects to move them into place. It could also be as simple as lifting other objects.

Object to move can be used as a platform
Focus on rotation of wheel

This would use the weight/friction of rope to rotate/spin the wheel that it is on while rope is moved. I am not sure how well the HFFWS system works with this.

Build a Compound Pulley

Since system does not allow for setup of complex block and tackle style pulleys, setup the environment for the player to build their own. This gets around the inability of the system itself by letting the player set it up. This would require building the environment in such a way (such as veritcal moving platforms or stairs around) to let the player move the rope through a series of wheels to build this pulley.

Lift Heavy Object

One end attached of the rope is fixed to a very heavy or massive object. The other end is where work is done to try to lift the heavy object. Examples of this could be a large door or simply a heavy platform. The system focuses on maximizing the overall force output. This will mostly be done by focusing on the free end of the rope, but applying an aiding upward force to the heavy mass may also be factored in.

Online Multiplayer Networking Solution Tutorial Using Unity and Mirror - Tutorial by: Jason Weimann

February 2, 2021 Networking Online Multiplayer Unity & Mirror Title: Let's build a 4-Player Networked Game LIVE - Online Shooter (with Mirror & Unity) By: Jason Weimann Youtube - Tutorial Description: Intro to using Mirror for networking online multiplayer play in Unity development. Introduction This tutorial has Jason Weimann implementing online network play into a basic Unity twin-stick shooting game. They use Mirror, which is a Unity asset used for simplifying the online network synchronization process. This is a live implementation where they work through many errors transferring a game from simply working locally to working with a host/client relationship. Mirror Mirror - Home Page Mirror is "a high level Networking API for Unity, supporting different low level Transports" (from Mirror themselves). It is a clean solution for implementing a quick and simple online networking option for Unity projects. The core components breakd

Exporting FBX from Houdini with Color

April 17, 2019 Exporting From Houdini FBX and Color Information Exporting the Model Using my balloon Houdini example from class, I was able to export the geometry using the Educational version (the Apprentice version does not allow exporting FBX, but you could export an OBJ for my purposes possibly). This was very straight forward, as you can just use File -> Export -> FBX in Houdini. Since I was doing this for a class to use in a Snapchat filter (using LensStudio), I wanted to reduce the poly count a lot. I opened the FBX in Maya and used a basic Reduce to reduce the poly count a lot before exporting that for use in LensStudio. While this was good enough to export the geometry, I could not get any of the color information to come with it. I originally exported out an OBJ and had the same issue, so I exported FBX in hopes it would keep the color information somehow, but this was not the case. Exporting the Color Information My first thought to get the color

Houdini Assignment - Fuse and Group

Image
April 8, 2019 Houdini Assignment Fuse and Group I worked on a Houdini class assignment to make a basic model and decided to try and create the bulb on the back of a Bulbasaur, a Pokemon that is half plant and half dinosaur. I figured I could use a lot of the basics we learned in class to get me pretty far, while also needing to cover a few new things to get it exactly how I wanted it. In class, we created a basic hot air balloon. This consisted of tracing a curve over a background reference image of a hot air balloon, creating a section of the balloon from this original curve, then replicating that section as many times as needed to fully encompass the full balloon. These were a lot of principles I used for creating my bulb. The biggest hurdle I needed to overcome was that that top of each of my sections would all need to connect at a single point, so I would need some additional nodes after simply creating a "left" and "right" variation of my addit
