[behavior] rex_spline

See this demo first ( Capx ),

• click text "start" to stat moving
• drag the green way point to change the path

Document, plugin and sample capx file are included.

Compare with Pode 's SplinePath behavior

• my spline behavior can assign a constant speed. Pode's can not assign speed and the moving speed is not constant.
• my spline behavior supports official save/load

Here is my new spline behavior.

Thank you for this!

Looks like there's a bug for when its not looping:

https://www.dropbox.com/s/uzg3ns9f8jtd3 ... .capx?dl=0

And its not looping when it's set to yes.

Update

Fix the behavior of Looping.

Thanks for reply. I had fixed it.

Thanks a bunch.

Really been wanting something like this.

Great!, watching the documentation I observed that "tension" is included, perfect.

Its not a real big deal, but as a suggestion it could use some point indexing like the path finding behavior does.

xy at point index, and current index, etc

It's not like we can't create our own lists.

Update

Add

• "Expression:Point" to get all points in JSON, or a point in JSON, or X/Y co-ordinate of a point.
• "Expression:PointsCount" to get amount of points
• "Expression:CurSegP0", "Expression:CurSegP1" to get the point index of current segment ( moves from Expression:CurSegP0 to Expression:CurSegP1 )

See the document and sample capx.

Good suggestion! I had added them.

I'm not seeing how this works:

Expression:Point

Get points or a point or x/y of a point. Add 1st parameter for index of point, add 2nd parameter "x" or "y" or 0 or 1 to get x/y of a point.

The expression just shows:

Sprite.Spline.Point

Update

Get X/Y co-ordinate of start or end point by

Expression:CurSegP0( 0 ) or Expression:CurSegP0( "x" ) , X co-ordinate of start point

Expression:CurSegP0( 1 ) or Expression:CurSegP0( "y" ) , Y co-ordinate of start point

Expression:CurSegP1( 0 ) or Expression:CurSegP1( "x" ) , X co-ordinate of end point

Expression:CurSegP1( 1 ) or Expression:CurSegP1( "y" ) , Y co-ordinate of end point

newt

See the sample capx in document.

rexrainbow I got an error when opening your capx demo project. Also tried to access the 'CurSegP0' expression in the expression list, but nothing shown there.

A bug maybe?

edit: FYI, my plugins are all up to date and i'm currently using C2 beta release 230

edit #2: Sorry.. sorry... my mistake. i didn't realize the latest version. It's all fixed now.

Ok so to get the end x, and y of the current point:

Sprite.Spline.Point(Sprite.Spline.CurSegP1,"x")

Sprite.Spline.Point(Sprite.Spline.CurSegP1,"y")

newt

Or get position of end point by ( Expression:CurSegP1( "x" ) , Expression:CurSegP1( "y" ) )

Ok, that would be simpler.

Thanks again.
