everytime I try to make a render with sparks.js and Three.js, i get the same error :
Uncaught TypeError: Property '_easing' of object [object Object] is not a function sparks.js:304
Could you please tell me more? I don't understand how to fix this. Thanks.
(The tag sparks.js doesn't exist so I couldn't include it, due to my reputation, sorry).
The error is caused by using an old TWEEN constant as default value for Age action. Try to initialise Age explicitly like :
new SPARKS.Age(TWEEN.Easing.Linear.None)
