# How do I Set the Animation of an Object Based on Y-value?

This is a single chapter from the "Construct Starter Kit Collection". It is the Student Workbook for its Workshop.
• I have an object that uses path finding to move. If it is going left I want it to play one animation or if it is going right to play a different animation. I was think of using its Y coordinate do so but I do just can't figure it out.

In summary I was seeing if I could check the change in the Y coordinate to set the animation (Decreasing for left, Increasing Y for Right)

I am open to suggestions if you have an alternate method

Thank you, Nick

• The Y coordinate represents up and down. Try using the X coordinate.

• Whilst I am an idiot for making such a rookie mistake, that sadly did not solve my animation dilemma

• Save y to a variable LastY every tick. Compare current y to LastY to see which is greater and set the appropriate animation.

• Alright, try this:

+ Sprite: Is Pathfinding moving along path

----+ System: Sprite.Pathfinding.MovingAngle is between 90 and 270 degrees

-----> Sprite: Set animation to "WalkLeft" (play from beginning)

----+ System: Else

-----> Sprite: Set animation to "WalkRight" (play from beginning)

Instead of checking the x value, check the move angle. If it is between 90 and 270, the player is facing left. if not, the player is moving right.

• + Sprite: Is Pathfinding moving along path

+ System: Sprite.Pathfinding.CurrentNode ≠ Sprite.Pathfinding.NodeCount

----+ Sprite: X > Self.Pathfinding.NodeXAt(Self.Pathfinding.CurrentNode)

-----> Sprite: Set animation to "MoveLeft" (play from beginning)

----+ System: Else

-----> Sprite: Set animation to "MoveRight" (play from beginning)

Here's another option. This one uses the x coordinate if that is easier for you than the angle. Notice the use of the NodeXAt call. This gets the x coordinate of the node whose id you pass in.
