Hitbox Question

Hi there,
I have a question that remained unanswered from my previous post, so I figured asking the second part would help
Is it possible to use JSON to create a 100x100 hitbox for the below image? The image is 128x128, and I put a purple square to show where I want it to be. I tried making one using Physics Body Editor but it hasn't worked; Gamesalad just spits it out when I try to enter it in the custom hitbox section. The black sections are transparent in-game.

I use physics body editor also, try to make it not so much like a box....just change little so it draws some green lines in the editor
@freneticz Thanks man. I got the green lines like you said, but Gamesalad still spits it out, I think it's all of the fluff in the JSON code. Do your files usually look like this when they work?

I use PhysicsEditor as I found it easier and more reliable than PhysicsBodyEditor, but it's not free.
Here's what it produced for that image. I matched the purple box.
{ "rigidBodies": [ { "normalized":false, "rescale":false, "origin":{"x":0,"y":0}, "size":{"width":128,"height":128}, "polygons": [ [ {"x": 14, "y": 100 }, {"x": 14, "y": 0 }, {"x": 114, "y": 0 }, {"x": 114, "y": 100 } ] ] } ] }@Armelline You're a life saver, thank you so much for the hitbox code. I'll be sure to put you in the credits of my game
Happy to help! Let me know if you need any others done.
This is the software I used, but it's fairly expensive for what it is: https://www.codeandweb.com/physicseditor
