Learn states and transitions in an Animator Controller.
State Machine States
Each State inside an Animator Controller represents a specific animation state. For example, a character's hurt, death, or attack animations can be defined as separate states. An Animation Clip can be assigned to each state.
// Hurt
// Death
// AttackUnderstanding Transition Duration and Conditions
Transition settings determine how the change from one state to another occurs. When Has Exit Time is enabled, a transition can occur when the current animation reaches its exit time. Transition Duration controls the blending time between two animations.
// Has Exit Time
// Transition Duration
// ConditionsPractice Check the Transition Status
Check whether a transition is active on layer 0 of the Animator component. If a transition is in progress, print Transition in progress; otherwise, print No transition.
Starter code
using UnityEngine;
public class TransitionCheck : MonoBehaviour
{
public Animator animator;
void Update()
{
}
}Sample solution
using UnityEngine;
public class TransitionCheck : MonoBehaviour
{
public Animator animator;
void Update()
{
bool transitioning = animator.IsInTransition(0);
if (transitioning)
{
Debug.Log("Geçiş devam ediyor");
}
else
{
Debug.Log("Geçiş yok");
}
}
}Expected output
Geçiş yok
