Animation

Question 1

Animation controller asset

Answer 1

An animation controller asset allows you to arrange and maintain a set of animation clips and associated animation transitions for a character or object.
You have to place an animation clip into an animation controller to use it on a GameObject.

Question 2

Animation controller and animation clips

Answer 2

The animation controller has references to the animation clips used within it, and manages the various animation clips and transitions between them using a static machine, like a flow chart of animation clips and transitions

Question 3

Animation controllers and clips contains parameters and layers aswell.

Answer 3

Use the scroll wheel on your mouse to zoom in and out.

A key to fit all states into view

Question 4

Animation transitions

Answer 4

Animation transitions allow the state machine to switch or blend from one animation state to another.
Transitions define not only how long the blend between states should take, but also under what conditions they should activate. You can set up a transitions to occur only when certain conditions are true

Question 5

To set up a transition conditions, specify values of parameters in the Animator Controller

Answer 5

Your character may have a patrolling state and sleeping state. You could set the transition between patrolling and sleeping to occur only when an alertness parameter value drops below a certain level

Question 6

Naming Transitions

Answer 6

Transitions can be given a name by typing it into the naming field

Question 7

Transitions in the Inspector

Answer 7

The Inspector Window of a state shows the transitions the state uses.
Shows its name, tag, speed, motion, foot ik, write defaults, mirror and the Transitions.

Question 8

There can only be one Transition active at any time. But the currently active transition can be interrupted by another transition if you have configured the settings to allow it

Answer 8

True

Question 9

Transition Properties

Answer 9

To view properties for a transition, click on the transition line connecting two states in the Animator window. The properties appear in the inspector window.

Question 10

Transition Conditions

Answer 10

A transition can have a single condition, multiple conditions, or no conditions at all. If your transition has no conditions, the Unity editor only considers the Exit Time, and the transition occurs when the exit time is reached. If your transition has one or more conditions, the conditions must all be met before the transition is triggered.

Question 11

Transition Conditions consist of

Answer 11

An event parameter, the value of which is considered in the condition
A conditional predicate, if needed, for example, less or greater for floats.
A parameter value if needed

Question 12

Animation has Exit Time

Answer 12

If had exit time is enabled for the transition and has one or more conditions, these conditions are only checked after the exit time of the state. This allows you to ensure that your transition only occurs during a certain portion of the animation.

Question 13

To Manually create an animation controller

Answer 13

Right click on the project window and click Create, Animation Controller

Question 14

Unity Automatically creates an Animation Controller when you begin animating a GameObject using the animation window, or when you attach an Animation Clip to a game object

Answer 14

True

Question 15

The Animator contains

Answer 15

The base layer.
Parameters
Layers.
Sub state machine
States in the Animator, idle, attack, walking, etc
You also have an Enable Auto Live Link in the Animation Controller Window

Question 16

Animation controller parameter types

Answer 16

Int, integer, whole number
Float, floating point, a number with a fraction part
Bool, Boolean, true or false value, representsd by a checkbox
Trigger, a boolean parameter that is reset by the controller when consumed by a transition, represented by a circle button

Question 17

Parameters can be assigned values from a script using functions in the Animator class

Answer 17

SetFloat
SetInt
SetBool
SetTrigger
ResetTrigger

Question 18

How to call the Animator in script

Answer 18

Animator animator;
Void Start()
{animator = GetComponent() ;}
Void Update()
{ float h = Input.GetAxis("Horizontal");
Float v = Input.GetAxis ("Vertical") ;
Bool fire = Input.GetButtonDown("Fire") ;
animator.SetFloat("Forward", v) ;
animator.SetFloat("Strafe", h) ;
animator.SetFloat("Fire", fire) ; }
Void OnCollisionEnter(Collision col)
{if col.gameObject.CompareTag("Enemy"))
{animator. SetTrigger("Die") ; }
}
}

Question 19

Animation states

The basic building blocks of an Animation State Machine

Answer 19

Each state contains an animation sequence, or blend tree, that plays when the character is in that state.
Select the state in the Animation Controller, to view the properties for the state in the Inspector window.

Question 20

In the Inspector, the Animation State contains, Including its name and tag,

Answer 20

Motion, the Animation clip or blend tree assigned to this state.
Speed, if set to -1 goes backwards, the default speed of the motion for this state. Enable parameter to modify the speed with a custom value from a script. Ie, you can multiply the speed with a custom value to decrease or accelerate the play speed.
Motion Time, the time used to play the motion for this state. Enable parameter to control the motion time with a custom value from a script.
Mirror, This property only applies to states with humanoid animation. Enable to mirror the animation for this state. Enable parameter to enable or disable mirroring from a script.
Cycle offset, the offset added to the state time of motion. This offset does not affect the motion time. Enable parameters to specify the Cycle Offset from a script.
Fook IK, this property only applies to states with humanoid animation. Enable to respect Foot IK for this state.
Write Defaults, whether the AnimationStates writes the default values for properties that are not animated by its motion.
Transitions, the list of transitions originating from this state.

Question 21

What is the Any State in the Animation Controller

Answer 21

Any State is a special state which is always present.
It exists for the situation where you want to go to a specific state regardless of which state you are currently in.
This is a shorthand way of adding the same outward transition to all states in your machine.

Question 22

The special meaning of Any State

Answer 22

Any State implies that it cannot be the end point of a transition.
Ie, jumping to Any State cannot be used as a way to pick a random state to enter next)
