In LSL the rotation around z is done first, then around y, and finally around x. This is called the Euler representation of a 3D angle. Note that these three numbers are a vector type and not a rotation type, though it can represent the same information. In LSL, these three angles are expressed in radians instead of degrees, that is, a right angle is PI/2. Note that in the Edit window, the numbers are in degrees, that is, a right angle is 90. It is easy to adjust the Rotation numbers in the Edit window and see how the object behaves. This is used in the Edit window, for example, and is generally easy for people to visualize. Such a system is described in the excellent article About Coordinate Systems and Rotations by Timmy Foxclaw.Īnother way to represent a 3D angle is using three numbers,, which represent the amount which the object is rotated around each axis. To master rotations it is therefore essential to use a good naming system for your variables. There is confusion about the difference between an applied rotation and the rotation 'offset' between coordinate systems.The order in which translation and rotations need to be applied can vary from case to case.There are actually several different types of vectors ('dir', 'vec' and 'pos') that need to acted upon differently.

Nobody really knows what a quaternion is, or how to think about it (not entirely true, the brain just isn't good at thinking in 4 geometric dimensions).Rotations are often regarded a very confusing subject, where scripters use trial-and-error to get it right. There is also information about causing textures to rotate in textures. Quaternions is that they are not susceptible to gimbal lock.įor the complex inner workings of quaternion mathematics, see quaternion.įor a list of functions and events related to rotations see LSL Rotation Synopsis. You can think of a quaternion as four numbers, three of which represent the direction an object is facing and a fourth that represents the object's banking left or right around that direction. It is a mathematical object called a quaternion.

The rotation can be viewed as a discrete twist in three dimensional space, and the orientation of an object is how much it has been twisted around from whichever axes we are using - normally the region's axes. (Note that we try to write the type name in bold.) Public class ExampleScript : MonoBehaviourĬube1 = GameObject.CreatePrimitive( PrimitiveType.Cube) Ĭ = new Vector3(0.75f, 0.0f, 0.0f) Ĭ(90.0f, 0.0f, 0.0f, Space.Self) Ĭube1.GetComponent().lor = Color.red Ĭube2 = GameObject.CreatePrimitive( PrimitiveType.Cube) Ĭ = new Vector3(-0.75f, 0.0f, 0.0f) Ĭ(90.0f, 0.0f, 0.0f, Space.World) Ĭube2.GetComponent().lor = een Ĭ(xAngle, yAngle, zAngle, Space.Self) Ĭ(xAngle, yAngle, zAngle, Space.The LSL rotation type is one of several ways to represent an orientation in 3D. The rotation is controlled using xAngle, yAngle and zAngle, modifiable on the inspector. Add it onto any GameObject in a scene and hit play to see it run. This script creates two different cubes: one red which is rotated using Space.Self one green which is rotated using Space.World. If you de-select and the re-select the cube, the axes are shown in the same orientation as before.Ī cube not rotated in Global Gizmo Toggleįor more information on Rotation in Unity, see Rotation and Orientation in Unity.

Rotating the cube updates the rotation axes. So, a newly created cube uses its x, y, and z axis set to zero rotation.

Local rotation uses the coordinate system of the GameObject itself. If you de-select and then re-select the cube, the axes restart in world alignment. Moving these Gizmos rotates the cube around the axes. When you select a cube in the Unity Editor’s Scene view, rotation Gizmos appear for the left/right, up/down and forward/back rotation axes. So if you rotate a cube in world space, its axes align with the world.

World axis rotation uses the coordinate system of the Scene, so when you start rotate a GameObject, its x, y, and z axes are aligned with the x, y, and z world axes. You can specify a rotation in world axes or local axes.
