Mapping — In the last article, “Sending ether to a contract and withdrawing” we looked at a working example for using the address variable and msg object. …

Working with a single Image Target — In this article, we will have a look at AR using Vuforia Image Target feature. Image Targets represent images that Vuforia Engine can detect and track. These can be pictures in magazines, on posters or even back of a cereal box. Once detected, we can place whatever we have developed…

Sending ether to a contract and withdrawing — In the last article, “Understanding variables in Solidity” we looked at a number of variables, in particular the Address. In this article, we are going to demonstrate an example of a smart contract that will we can send money to, check it’s balance and then withdraw the money to an…

Understanding Variables in Solidity — We are going to continue on from the previous article where we created our first contract. In this article, we will look at some of the different variables in Solidity for storing information. Go ahead and create a new Solidity file and name it MyVariables.sol. …

Creating your first smart contract in Solidity — In this series, I am going to share with you my journey in learning how to become a Blockchain Developer. I am not going to explain what blockchain is or how it works as there are plenty of resources out there. We are going to use Solidity as the language…

Objective: Attacking using the new Input System — In this article, we will explore Unity’s new Input System to capture pressing the Space bar for attacking. I’ll be incorporating the new Input System into my next prototype but feel free to use a new project with assets you like. Create a Input Action asset file Firstly I will create a folder to store the…

Objective: Explain the shortcuts to making level design easier in Unity — When it comes to level design is very time-consuming. Here are a few tips to help streamline this phase of your project. Moving, rotating, or scaling an object in increments When moving an object around you may need to move it one unit to the left. Hold down the CTRL key while moving and it will move in…

Ability to throw objects — So far in this series, we can pick up and drop objects in our VR world. If you try to throw the object, as soon as you let go of the grabbed object, it drops straight to the ground. …

The ability to grab objects in the VR world — In this article, we will look at two ways for grabbing an object. First is using Kinematics technique, then have a look at using Fixed Joint technique, and then we will settle on combining the two. Kinematic Grabbing This technique is making the grabbed object a child of the hand, making it…
