Interaction Kit v3.0.1 Overview

Interaction Kit is an innovative and powerful system to handle practically any kind of interaction in your games. It is possible to build interactions with the kind of depth you’d see in popular RPG games. Anything from simple door triggers, switches, complex quests or even non-linear conditional speech can be built with InteractionKit’s incredibly easy to use visual logic system. The UI is powered by a very flexible editor that allows you to customise the placement, appearance and effects of your interface.

Interaction Kit has everything you need to make any GameObject interactive in a matter of minutes! The friendly editor allows you to choose from 6 RayCasting techniques that cover the majority of game genres as well as offering unprecedented control over collisions via a mix of layers and game tags!

Finally, the real power comes from the Interact editor which allows you to easily create conditional events just by pointing and clicking the mouse. Each event can trigger a wide array of built-in actions and you can even trigger external scripts! Maybe you want to create an interaction on a door, but only have it open if you acquire the key? Perhaps you want to build a conversation with an NPC that is different depending on the progress the player has made? All of this and more is possible with InteractionKit, the all in one power house of developing interactions!

Interaction Kit Tutorial Videos

1) Interaction Kit – Tutorial 1 – Basics

In this first InteractionKit tutorial, we take a look at implementing Interaction Kit into a basic FPS style game.

2) Interaction Kit – Tutorial 2 – Runtime Tools

In this video, we take a look at the different detection modes, how they work and how you can set them up to take advantage of different types of games.

3) Interaction Kit – Tutorial 3 – Building Interactions

In this video, we focus in on how to build interactions with 2 different examples. In the first we create a type of loot-style interaction that can be picked up. The second example shows how to build a sequential dialogue with an NPC using Interaction Kit’s powerful conditional events.
