Lynda.com: Become a Unity 2D Developer (Day 4)
UNITY 5: 2D BUILDING A TILE MAP EDITOR
According to the tutorial instructor, Jesse Freeman, this course will focus on understanding how to use the Tile Map Editor extension for Unity. Obtaining a strong foundation with the Tile Map Editor will enable me to create a tile map class, custom tile picker, a tile brush, along with creating custom menus.
This particular exercise was more or less a preview of what is to come. Nevertheless, I was able to add a custom menu option, specifically GameObject -> Tile Map. Luckily for me, it worked as expected. Not only did the menu option populate, it executed the code to add a Tile Map layer. Also, for the sake of showing work, I will include an alternate menu option that is very much "troll thing to do". **Did I just admit to hack'n my own application menu? It just renders an option titled as "Cereal Time!"**
Building a Custom Inspector
Creating a custom inspector item was fairly simple. The C# script was able to utilize the #UnityEditor and TileMapEditor class, which allows the option of creating a custom inspector GUI value.
Reading Sprites from a Texture
This lesson has been broken into 5 parts: Creating a Texture Picker, Showing a Warning Message, Calculating Tile Size, Calculating the Map Size, and Dynamic Pixels to Units. With that out of the way, onward with the lesson.
Creating a Texture Picker
It is safe to assume from herein, I will be utilizing C# scripts to modify all components of Unity. This lesson sorta flew over my head. This C# script modifies the Tile Map Inspector window to include a Texture Picker option. (located on lower right-hand side of Inspector palette image.)
Showing a Warning Message
You know how there are some titles that give it all away. Well, that is the case here. Showing a Warning Message is literally an exercise to display a warning message when something is wrong. In this case, it is a message when a texture is missing or simply unavailable.
Calculating the Tile Size
Pulling on the thread from the exercise above, the next step is to write a script that is able to determine the size tile that is being loaded. Notice on the example above, there is a field for Tile Size but with a value of "0x0". The displayed value does not reflect the attributes of the loaded texture image.
Using the C# scripts below, whenever a texture is loaded, it will display the dimensions of the loaded texture.
Calculating the Map Size
Setting up the script for determining the size of the grid was a matter of developing a formula and applying it within the code. Granted, I'm no math wiz so I'm glad this is just me following a tutorial. In any case, below is a screenshot of the C# script along with the successful outcome. Admittedly, this took a while to get working. There were a few typos that rendered the code useless. Quite disastrous when my code came to a screeching halt due to a misplaced comma.
Dynamic Pixels to Units
This tutorial was a bit of eyebrow raiser. With that said, I was a bit lost in regards to it's application, until the very end. Ultimately, this enables the developer/designer to ensure that the images loaded are correctly listed in regards to units of measurement.
