In this Unity game development tutorial we're going to look at how we can rotate an object so that it faces the direction it’s moving in. You can either watch the video version below or continue reading for written instructions. Right, let's get started by creating a new 3D project in Unity Hub. We'll add a Plane to represent our floor by clicking the plus button on the Hierarchy and selecting 3D Object->Plane. We'll set the scale of the Plane to ten on the X axis and ten on the Z axis. Next, we'll create a material to change the colour of the floor. To do this, we'll click the plus button on the Project panel and select Material. We'll name this material 'Floor'. We'll then click on the box next to Albedo in the Inspector panel, and choose a green colour. We can now drag the material on to the Plane to assign it. We now need a character to move around our scene. For this we'll head over to the Asset Store by selecting Window->A...
In this Unity game development tutorial we're going to look at how we can create realistic looking terrain from real world height data. You can either watch the video version below or continue reading for written instructions. You can hand sculpt terrain using the tools in Unity, but in this tutorial we're going to look at an alternative - using images known as heightmaps. A heightmap is a grayscale image that contains height information. The darker pixels represent areas of low height and the lighter pixels represent higher areas. Below is an example of a heightmap. There are various sources online that you can get free heightmaps, but we're going to look at this one that allows you to create heightmaps of the real world - https://cs.heightmap.skydark.pl/ This resource was created for generating terrain for the game Cities Skylines but it will work just as well in Unity. Basically, it allows us to select any 18km square area on the map and then create a hei...
In this Unity game development tutorial we'll look at how we can process player input from a gamepad or the keyboard and use that to move an object within the game. 1. To get started let's create a new 3D project in Unity Hub. 2. Add a Plane to the scene to represent our floor by clicking the plus button on the Hierarchy panel and selecting 3D Object->Plane. 3. We'll use a capsule to represent our player. Add this to the scene by clicking the plus button on the Hierarchy panel and selecting 3D Object->Capsule. 4. Set the position of the capsule to (0, 1, 0) in the Inspector panel to position it on top of the plane. 5. In order to process the player input and use it to make the capsule move we need to create a C# script to contain our logic. To do this click on the 'Add Component' button in the Inspector panel, search for script and click 'New Script'. Call the new script PlayerMovement. This will create a script component attached to the capsule. 6. Do...
