Tower Defense Tutorial

Episode 22 – Main Menu

Youtube - How to make a Tower Defense Game (E22 MAIN MENU) - Unity Tutorial

Ep. 22

In this tutorial we created the Main Menu scene for the game.

We duplicated the original game scene to start, and deleted out everything except the Light, Main Camera, and Environment. Then we only kept the Ground Plane from the environment. We then added a Standard Turret Prefab to be a central object for our menu.

We then edited the sky box to something other than the Unity default. We selected Solid Color for it, and used the color picker to pick the top most color of our ground plane so the sky matched this very final gradient of color. This made it seem like the background was one solid, endless color gradient for the most part.

We then created a World Space canvas with text fitted to it for our PLAY text. We placed this on top of the turret prefab in our menu. We then wanted to make this text clickable, so we just added a Button (script) component. This basically turned the text into a button for us. We could even add our previous animation by simply adding an Animator component and selected our Button Controller for the Controller.

We then created the MainMenu script which will hold the main functionality of this scene. This started by creating public Play and Quit methods for our Play Button and Quit Button. Quit was just Application.Quit, and Play loaded our MainLevel scene.

Finally, we added a bit of animation to our Main Menu to utilize the fact it is set in a 3D environment. We added the two button canvases as children to the PartToRotate object of the turret, and created a quick animation for that that just rotated the entire turret and UI element back and forth a bit over time. This really made the menu feel alive and 3D.

SUMMARY

  • To set current editor view as camera view: select camera and press: Ctrl + Shift + F
  • Set skybox to solid color and use color picker to select farthest/top most color of ground plane for a quick/easy way to make ground and sky look like one coherent background
  • When referencing scene names, make a string and set its value to that scene name so if at any point you want to change the scene name, you just change that string variable’s value and it will fix it in all locations needed

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

Sebastian Lague A* Tutorial Series - Path Smoothing - Pt. 08 and Pt. 09

December 13, 2019 A* Tutorial Series A* Pathfinding (E08: path smoothing 1/2) A* Pathfinding (E08: path smoothing 1/2) Link - Tutorial 1 By: Sebastian Lague A* Tutorial Series A* Pathfinding (E09: path smoothing 2/2) A* Pathfinding (E09: path smoothing 2/2) Link - Tutorial 2 By: Sebastian Lague A* Pathfinding (E08: path smoothing 1/2) Intro: These tutorials both covered the same general topic of smoothing the path of the unit. Theory Currently the units follow the path by making a straight line from one point to the next, which looks unnatural. To remedy this, they suggest a path smoothing technique. This system starts with each point having a small line pointing directly to the previous point, whose length is called the "turn distance". This line then has a perpendicular line emanating from the end, called the "turn boundary". Once the unit passes this turn boundary, it will start to turn towards the next point in the path (inste

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
