First, let’s add a text element to the scene. You can add text using the Gameobject>create>other> UI>text option. Once you have added it you will see a text element in the hierarchy. Select the UI gameobject and you can see the options in the inspector window like the one in the image below.
Unity gives you the option to change the font, font style, font size, alignment. It also has the option to wrap text. Material is one option that many people underestimate. You can get a theme-based UI with the material option. Unity asset store has a lot of UI materials that you can use to get the right-looking UI for your game.
Raycast target is used when you want the text to be clickable. Most people use buttons for this purpose, but in some scenarios, text looks like the best fit. Don’t enable this option if you don’t want your text to work as a button. Raycast target is enabled by default when you add a text object to your hierarchy, don’t forget to disable it. Many texts with Raycast targets can add to performance issues. You might not notice it in smaller games but when you are making complex games every aspect that can boost performance needs to be addressed.
Unity Rich Text
You can see a check box in the above image that says the rich text. Normally if you enable it you won’t see any difference in the text you have added. What it does is, it enables the markup text formatting options. Markup text is similar to HTML formatting. You can do a lot of innovative things with this. Let’s see what are the options available and how to use them.
1.BOLD, Italics and Size
As you can see in the Unity inspector, there is no option to make the text bold or italics. With the Unity rich text option, you can do it. You can use “<b>” to make some characters bold., “<I>” is used for italics, and “<size>” is used for font size. Font size can also be set using the inspector window but if you want a certain portion of the text in a different size you can use the “<size>” attribute.
For example you can type ” <b>This</b> is a <i>test</i> <size=50>sample</size>”. This way you make your text look better than the plain version that comes by default.
2. Material ,Color and quad
HTML tags <color>,<material>,<quad> is used to specify the color ,material and quad for the text.
The main reason to use rich text formatting is to get different styles for words in a single sentence similar to the size attribute. Let’s see an example for better understanding.
Lets take the sentence ” Unity Rich Text is really useful” and apply different style to different word .Enter this in the text box to test ” <color=”blue”><b>Unity</b> <I> Rich</I> text is really useful<\color>”. The output will look like this
