Job ID: 33045482

Budget: $15 – $25 USD

I have a PDF reader in my project, with multiple UI buttons. Each button opens a PDF chapter from a digital textbook.
I do not have enough C# experience and just need someone for an hours work to write the couple of lines of code to action the OnClick event in Unity to open each chapter of my textbook.
