How do I make my boss switch different costumes if moving left or right?

The game is here: https://scratch.mit.edu/projects/1367688394
btw the boss is on the third backdrop; play through to test it.

I wasn't able to get to the boss because your game is unintuitive, but what I think you are trying to do would be inefficient. Instead you should set the boss' rotation style to left-right (only doable with a block in the motion category, but even clicking the block in the pallet will save until the block is triggered again), and have it constantly point towards the player.

I assumed that you wanted a different set of left and right costumes, which I tried to show why you might want that by adding some badly drawn shading on the tree boss's costumes, otherwise you don't need to actually switch costumes when you switch directions - but I was trying to answer the question you asked.

I modified the tree boss code in this remix: https://scratch.mit.edu/projects/1370218728/ to use a different set of right and left costumes and with walking animation.

I also changed the stage to quickly go to background #3 so I could get to the part where the tree boss is walking toward the player.

Also, please add an attack mechanism because your code doesn’t work when I tested it

I was just trying to answer your question about the costume changes. If this is what you needed then I assumed you could continue to make progress on your project. However, the question is ‘do you need a separate looking set of left and right costumes or do you just need two walking costumes that can be pointed to either left or right.

But about the attack, you could change that repeat 0 block to let the ‘if touching player then broadcast damage’ blocks run. Putting those blocks in a repeat 0 loop is just a way to keep them in the script but not have them ever execute.

when [right arrow v] key pressed
switch costume to [whatever...? v]
when [left arrow v] key pressed
switch costume to [whatever...? v]

Using the when key pressed hatblocks are not recommended instead use forever loops and if statements but thats besides the point since this is a boss i would do this

when green flag clicked
set rotation style [dont rotate v]
set [steps v] to [number of steps you want]
move (steps) steps
point in direction (steps)

This works bc if your moving in a positive number you will point right and if negative you will point left

You need left-right to do this, not don't rotate
