Enemy AI (part 2)

Pausing the movement of your Enemy during Idle Animation

Now that we have our enemy AI moving towards point A to point B, it is time to make the enemy pause during the idle animation.

Moss Giant Script:

Within the Moss Giant script we are going to need to gain access to the Animator component, so create a handle for the Animator. Since the Animator is located as a child object, we need to use the “Get Component in Children” function.

Next in the override Update method we need to pause the movement only when the idle state is playing. In Unity there is a special script that can track and compare the current state to the require state to toggle an action. This method is called “Get Current Animator State Info(0)”. The int number that is in brackets determines the layer of the Animator you are working on. Base Layer will always be Zero. This will allow Unity to check for states and we can use the “Is Name” to search by a string.

Since we don’t want the Moss Giant to do anything other than play the Idle animation, we can just use the “return” function to let the animation play until finished. Then the Animator would transition to the walking state causing the movement to happen.

To pause the Moss Giant when it reaches to the second point, we can toggle a parameter to let the idle condition play just when the Moss Giant reaches the next destination.

The best way to do this is inserting the Trigger condition just when the Moss Giant as reach the current position. We have the best situation within the Movement method where we setup the next destination via ping pong movement.
