Prefab Scripts

info

In order to copy and paste the scripts below without hassle you will need to have the sample package imported via unity package manager. If you need to install the sample package you can follow the install guide in our getting started section here.

The login scene​

You'll notice when you import the samples into the project that some scenes are added to your build configuration. You'll want to keep the login scene as the first scene as it's needed to initialize web3 to create a wallet connection. You can remove the rest and add a blank scene as your 2nd scene in build settings. We'll use this 2nd scene to drop scripts in and out of for testing purposes. Make sure your 2nd scene has an event system present in the hierarchy or the scripts won't work. You can right click in the object hierarchy on the left and go to UI -> Event system to add one if it isn't there.

Adding a script to a scene for testing​

If you right click in the unity explorer you can create a c# script. For example we're going to test erc20NameOf to get the name of an ERC20 token from chain data. Right click in the editor file explorer and create a new script, attach this script to an empty object in the scene next to the editor system. Name the script erc20NameOf, place the code below into it and press save. Once saved you can go back to the editor, create a button and assign the scripts public function to a button press event on the right. You can do this by finding the objects properties on the right, scrolling down to button and adding an event. Just drag the object with the script into the button event area and choose the starting function of the script.
