Unity: Throttle Controller
Posted by Dimitri | Filed under Programming
This Unity programming tutorial will explain how to create a script that translates the containing game object forward at a pre-defined speed rate. This rate is controlled by a throttle much like the ones found in boats, planes or even trains. As usual, a Unity project with a working demonstration of this code is available at the end of the post.
The inspiration behind this tutorial came from the first Half-Life game, in which a train at the end of the tutorial level can have its velocity is gradually set by the player. Some of you may not remember how it looked like, so here’s a screenshot: (more…)
Unity: How to make an overview map
Posted by Dimitri | Filed under Programming
This Unity tutorial explains the required steps to create a map that displays the level in a top-down view. For a real-time, precise map, an orthographic camera can be placed on the top of the map and set to exclusively render a specific layer. However, this post isn’t about creating a precise map, instead it shows how to create a stylized one. A Unity project with everything explained here is available for download at the end of this tutorial.
The first step is to create a plane by clicking on GameObject->Create Other->Plane. Resize it underneath your level, making it have the same size of your scene, not bigger or smaller, just enough to fit all of the elements inside it. (more…)
Unity: Scaling the GUI based on the screen resolution
Posted by Dimitri | Filed under Featured, Programming
As hinted by other posts, here, you will find how to properly scale the GUI elements based on screen resolution. As one may have noticed, Unity doesn’t scale the GUI elements based on the screen resolution, requiring a script to do the job, which is explained in this post. I will assume that the reader already knows how to create and render GUI elements in Unity using the MonoBehaviour’s OnGUI() function and GUISkin objects.
The best way to explain how to properly scale a GUI element is through an example. That said, for this post, let’s assume that we wanted a yellow rectangle to be rendered at the top left and bottom right corners of the screen, like this: (more…)
Unity: How to use a GUI Texture to play fullscreen videos
Posted by Dimitri | Filed under Programming
Warning: this tutorial only works with Unity Pro because the free version doesn’t come with video playback support. The code was created and tested with Unity version 3.3. It won’t work for versions 2.6 and below (requires some adaptation).
This Unity post explains how to set up a GUI Texture at the Unity editor and the code necessary to play a fullscreen video, that can be used for the studio logo animation at the beginning of the game, the game’s intro or any other video that needs to take the whole screen. It also explains how to properly scale the video based on the screen dimensions. At the end of the post, a Unity project featuring all the code explained here is available for download.
Unity: How to create a GUI Sprite Sheet – Part 3
Posted by Dimitri | Filed under Featured, Programming
The final part of a series that explains how to create a GUI Sprite Sheet in Unity. This post will focus on explaining how the code works. For those who haven’t read the first and second parts, please do before going any further. As most post series in this website, there is a download with everything that had been explained at the end of the post.
With all images and the GUI Skin already set at the Unity Editor, now we just need some code to render the GUI on the screen. The following script correctly renders separately each element from the sprite sheet, and it’s attached to the Main Camera:
