Invalid JSON prompt
I just spent forever working on this custom shape with Physics Editor and GS does not accept it. getting invalid json prompt. anyone have any idea what could be wrong?? I really need this to work because the sprites that GS creates are a bit too large to size down to make invisible walls. the image is 1920x1080.
Comments
So I haven't actually looked into this, but a few thoughts:
Creator may have a limit on the complexity of the collision shapes.
Box2D only accepts convex shapes, so each shape that has a concave area is really multiple collision objects together. If you're doing the whole maze, that may just be too much.
While it's annoying you may be better off breaking your maze into building blocks and adding the shapes to those.
@sinbot Can you post the JSON code here? I remember the export script for exporting from PES by default does not handle multi-polygonal collisions correctly, but it can be modified to do so. Here is an example below:

Back when this was first introduced GS staff swore the exporter addon was fine. But myself and others had many issues. See this thread for work-arounds and information:

Here is the old script vs a modified script:
Old:
{ "rigidBodies": [{% for body in bodies %} { "normalized":false, "rescale":false, "origin":{"x":{{body.anchorPointAbs.x}},"y":{{body.anchorPointAbs.y}}}, "size":{"width":{{body.size.width}},"height":{{body.size.height}}}, "polygons": [{% for fixture in body.fixtures %}{% for polygon in fixture.polygons %} [{% for point in polygon %} {"x": {{point.x}}, "y": {{point.y}} }{% if not forloop.last %},{% endif %}{% endfor %} ]{% if not forloop.last %},{% endif %}{% endfor %}{% endfor %} ] }{% if not forloop.last %},{% endif %}{% endfor %} ] }When it should be closer to this:
However for it to be 100% correct you'd want to use this script but remove the last comma on the end block since no further collisions blocks occur. There is probably a better way to write this. Maybe someone can take a look.

this is the code for the collisions json. far as I can tell it looks correct but then again I am in over my head with this lol
That does look correct. I guess it's just too complex as Adent said.

so just for the record in case someone happens upon this thread with same issue.. it does in fact have to be one solid shape. It can be angular of course but all the vertex must be connected.
