getMovement (moveAmount) -> Amount to move as [x, y]

Enemy getMovement will first call determineState before doing super.getMovement

The enemy is the same as the character, except it

determines it’s own next state, rather than the player

Overrides gma.moveable.getMovement

Parameters
moveAmount	Number	The amount the character should move

determineState (moveAmount, manager)

Determine the state of the enemy for the next movement

- Calls behaviour__jumping if it has jumping tag

- Calls behaviour__patrolling if it has patrolling tag

- Calls behaviour__platformer if it has platformer tag

Parameters
moveAmount	Number	amount to move; based on delta from twitch
manager	gma.manager

collided (where, focus, focusSide, focusVector)

Enemy looks for rebound and weakhead tags as well as what super.collided looks for

It will also look for deathtouch, if enemy is still alive after all other checks

Overrides gma.shapes.rectangle.collided

Parameters
where	gma.constant	Side of this object that was collided with
focus	object	Thing we collided with
focusSide	gma.constant	Side of the focus object that was collided with
focusVector	[x,y]	Amount focus is trying to move

behaviour__jumping (moveAmount, manager)

Makes enemy jump when touching ground

Parameters
moveAmount	Number	amount to move; based on delta from twitch
manager	gma.manager

behaviour__platformer (moveAmount, manager)

Makes enemy turn around when reaching the edge of the platform it is currently on

Parameters
moveAmount	Number	amount to move; based on delta from twitch
manager	gma.manager

behaviour__patrolling (moveAmount, manager)

Makes enemy patrol a range

Requires self.limitLeft and/or self.limitRight properties

Parameters
moveAmount	Number	amount to move; based on delta from twitch
manager	gma.manager

collided__rebound (where, focus, focusSide, focusVector)

Makes enemy turn around if it hits something

Parameters
where	gma.constant	Side of this object that was collided with
focus	object	Thing we collided with
focusSide	gma.constant	Side of the focus object that was collided with
focusVector	[x,y]	Amount focus is trying to move

collided__weakhead (where, focus, focusSide, focusVector)

Makes enemy die when character hit it’s top

Parameters
where	gma.constant	Side of this object that was collided with
focus	object	Thing we collided with
focusSide	gma.constant	Side of the focus object that was collided with
focusVector	[x,y]	Amount focus is trying to move
