Failed to create effect

[Ingo Chou]

Hi,

 

I create effect with API :

 

var eff =  engine.createEffect("shader/myfx", ["pos","nor","uv"], ["wmat", "vmat", "pmat"], ["bumpsamper", "diffsamper"], "");

 

if(!eff.isReady()) {return false;}

 

But failed. It always returns false;

 

What causes it?

 

How can I get the error information ?

 

Thanks for any help?

First, it looks like createEffect is asyncronous, because it is loading files, then compiling.  Your code is not valid. You need to assign callbacks to the createEffect() method:

https://github.com/BabylonJS/Babylon.js/blob/master/src/babylon.engine.ts#L1236

 

2nd, the effect is passed in the callbacks, so you could check getCompilationError() method:

https://github.com/BabylonJS/Babylon.js/blob/master/src/Materials/babylon.effect.ts#L142

Thanks for your reply!

 

I set onCompiled callback and onError callback like this:

 

engine.createEffect("shader/myfx", ["pos","nor","uv"], ["wmat", "vmat", "pmat"], ["bumpsamper", "diffsamper"], "", function(){alert("compiled")}, function(){alert("error")} );

 

But the callbacks have never been called.

 

And it's state is always NOT READY.
