undefined error in Safari but working fine on others

[nardove]

I'm getting the following error in Safari:

TypeError: 'undefined' is not a function (evaluating 'this.path.add( point )')

But it works fine on Chrome, this is a very old code and I only spot that error after updating Safari.

Any help will be much appreciated

It would seem that you have an undefined variable or object being passed. 

Do you have more code ?

thanks

Hi Nick,

This is the bulk of it:

function Jelly() {

this.path = new Path();

this.location = new Point( -100 , Math.random() * (view.size.height * 0.5) );

this.velocity = new Point( 0, 0 );

this.acceleration = new Point( 0, 0 );

....

this.init = function() {

// Creates body path

for ( var i = 0; i < pathRes; i++ ) {

var theta = angle * i;

var thetaUp = theta - (Math.PI / 2);

var point = new Point({x: 0, y: 0});

// Upper side of the body

if ( theta < wrapAngle ) {

point.x = Math.cos( thetaUp ) * pathRadius;

point.y = Math.sin( thetaUp ) * pathRadius;

}

// Inner side

else if ( theta > wrapAngle && theta + (angle * 2) < wrapAngle + Math.PI ) {

point.x = Math.cos( thetaUp ) * pathRadius;

point.y = Math.sin( thetaUp ) * ((-pathRadius * 0.85) + pathRadius * 1.25);

}

// The other upper side of the body

else {

point.x = Math.cos( thetaUp ) * pathRadius;

point.y = Math.sin( thetaUp ) * pathRadius;

}

pathPoints[i] = point;

this.path.add( point );

}

Hi Nardove,

What is pathRes?

thanks 

Nick

[nardove]

Its a variable that contains the resolution or number of points of the path shape I'm trying to draw, hte weird thing is why it works in Chrome and used to work in Safari until I update it, still need to make it work in it ;)

[nick hulea]

I think somehow the object is not returning but only for safari

what is pathPoints[i]?

I feel like somehow its returning a string not an object but I am on a pc so I literally never use safari. 

thanks 

[nardove]

pathPoints is an array that contains all the points that the form the shape, I use it to do other calculations later on for other stuff ;)

Are you using PaperScript or JavaSCript? If JavaScript, are you injecting your code into the global scope through paper.install(window)? And what version of Paper.js are you using?

OK, solve the issue by updating paper.js, it used to work on previous versions thats why I didn't think about updating the lib 

Thanks!

Yeah Apple introduced a change in Safari 7 that broke older versions of Paper.js if you injected into the global scope (which isn't really such good practise, so we should perhaps stop recommending it :).

Updating solves it.
