Path Animator Script

Hi! Tell me if it is possible to use your script to make an animation for the bus doors. I'm applying an example.

Hello, I try to use or open the script but I have this problem, how can I fix it? thanks in advance!

Hi! Thank you for the tool, that's amazing.

I've just learned how to use it, and I stopped on the 4th tutorial. My object just rotating on his place and never follow the PATH. It works perfectly without the RFUN layer. With TFUN everything is all right :)

Also, something goes wrong with LOOKIT layer. Object just freeze rotated on one place and doesn't move.

I think, both errors have the same reason, but I can't solve it.

Hey, there's a weird thing that happens when I make the path shorter: Instead of the object going through the path once at the expencted speed, it instead goes around the path multiple times at a speed that's many times what I'd expect. What can I do to fix it?

Thanks for making this script ! it helped me a lot :D
I.... can't donate, but I wish I could. Maybe in the future...

I think I have found an error that could be improved. Steps to reproduce:

1. Create manually a layer ResultLayer with no content or by doing an animation, selecting all frames of animations, and then deleting the content of ResultLayer (not the layer itself, just the drawn pixels).
2. Select all needed layers for the animation
3. Run the script
4. It should give the error message --> path_animator.lua:409: attempt to index a nil value (field 'integer index')

I noticed that deleting or refilling ResultLayer with ctrl+Z solves this, but I think it would be better to just let the script run with default values as if that layer is not there (The "create a new ResultLayer checkbutton" could be locked in Unchecked).
Another workaround is to give a more descriptive message for the user, maybe saying that ResultLayer should be filled with animation content to restore the previously used values or non-existent.

I assumed a lot here (didn't read the code), but even if I'm wrong in my assumptions I think a more descriptive message for every possible console error message is needed. This would make the tool easier to use.

Hey! This looks awesome! Quick question: can I make a prexisting loop (say, pacman ghost looking right than left) to animate alongside the path too?

Been using this tool successfully for ages, love it. Lately though having a funny issue, no matter what I do, I cannot get my train to go from right to left. It insists on only going from left to right, (no matter where I put the white pixel.) Cant work out what I'm doing wrong.  

hi gar! I recently picked up your tool and have one small issue! whenever creating any form of rotation, the sprite I make is replaced with a large, black box

Hello, I made a stupid mistake when I first use this tool, I did nothing to the PATH layer, then run the script, set duration time to 8,click the Animate it button, then the alert window jump out.

Hello, I follow the tutorial and press the Animate it bottom, but it jump out a window of this 

what is the problem?

How do I make something rotate in place?

Hello, I'm a programmer, the artists of my team told me about 2 problems of the tool when trying calculate the path.

First is this one of pixel perfect paths not possible:

it can be easily solved by changing the order of the explorationVector components to this one:
explorationVector = {Point( 1,  0), Point( 0,  1), Point(-1,  0), Point( 0, -1), Point( 1, -1), Point( 1,  1), Point(-1,  1), Point(-1, -1) }

It is on the line 572. That way horizontal/vertical movements will have priority over diagonals.

Second thing is not actually a problem with your program but with aseprite (I think), it creates the same effect of the image not following the path but staying at a single point with weird movements. The problem is with transparent pixels with colors, like a pixel with 0 alpha but 255 of red component, I don't know why aseprite allows this pixels to be created or why the artists of the team created some of those, but the thing is that they are a problem, that some might not notice, and it can be solved easily by using the Magic Wand tool outside of the path line and clicking delete. It can also be identified by telling aseprite to draw an outline (with the convolution matrix- outline-transparent-layer).

Have a good day, Buena suerte!

can you make a tutorial on the scale thing?

if it's used like scale: easy inout, start scale: 1(%), end scale: 50(%), it creates a lot of tabs, is it on purpose? It looks like it never ends

So i just downloaded and idk if this is a known issue that has a resolve but my animation is not smooth. its clunky at best. after trying out a smaller scale animation it seems to render the frames on opposite side of the loop and alternate frames instead of being smooth and gradual. is there a solution that i just cant seem to find? or is this an issue?

HELP ! So I downloaded this and it works perfect however I have one question. I'm into side scrolling animation such as a car driving on the street w building going left to right so when I found this I was amazed. However, after using it I noticed I can't start a path off screen. Is there any way to fix this?? I need the images to start off the screen on the left ------> go all the way over, then go off screen on the right. Is that possible with this path animator? 

What does the RotAux layer do? You showed it in FAQ 7 but I don't think you explained what it does

Great addition to  Aseprite! Thanks for sharing!
