I do not know how to modify ,THanks!

Lx, Newbie Posted: 22 February 2013 03:06 AM Total Posts: 2 [ # 2 ] the error is: 156 line 1119: Access of possibly undefined property viewDirFragmentReg (static type away3d.materials.methods: CompositeDiffuseMethod references). 157 line 1119: Access of possibly undefined property normalFragmentReg (static type away3d.materials.methods: CompositeDiffuseMethod references). I used the away3d-core-fp11_4_1_0_Alpha.swc ,I use flash cs6.Thank you.

owntheweb, Jr. Member Posted: 13 March 2013 03:34 AM Total Posts: 32 [ # 4 ] Hello, I seem to be running into the same issue as well, while pulling the globe tutorial into a fun Mars project. I took it one or two steps at a time and all was well until adding the custom diffuse method - same errors. I started using the src you linked to (may have been using it already). The issue remains. Any thoughts on where I might be going wrong? I’m using Flash CS6 if that helps. Thanks for helping point me in the right direction. I’ll post if some sleep resolves the issue first (most often does). ===== Current wild guess: A global non-existing CompositeDiffuseMethod attribute is being accessed from within modulateDiffuseMethod. Am I wrong? I’m setting the diffuse method like this: `_atmosphereDiffuseMethod = new CompositeDiffuseMethod( modulateDiffuseMethod );` The modulateDiffuseMethod is trying to access attributes that don’t exist according to the current docs or new CompositeDiffuseMethod.as: http://away3d.com/livedocs/away3d/4.0/away3d/materials/methods/CompositeDiffuseMethod.html private function modulateDiffuseMethod( vo:MethodVO, t:ShaderRegisterElement, regCache:ShaderRegisterCache ):String { //craziness var viewDirFragmentReg:ShaderRegisterElement = _atmosphereDiffuseMethod.viewDirFragmentReg; //???? var normalFragmentReg:ShaderRegisterElement = _atmosphereDiffuseMethod.normalFragmentReg; //???? //end craziness ;) var temp:ShaderRegisterElement = regCache.getFreeFragmentSingleTemp(); regCache.addFragmentTempUsages( temp, 1 ); var code:String = "dp3 " + temp + ", " + viewDirFragmentReg + ".xyz, " + normalFragmentReg + ".xyz\n" + "mul " + temp + ", " + temp + ", " + temp + "\n" + "mul " + t + ".w, " + t + ".w, " + temp + "\n"; regCache.removeFragmentTempUsage( temp ); return code; } Edit: Still waking up, but so far I found protected _viewDirFragmentReg and _normalFragmentReg at CompositeDiffuseMethod’s base. No dice yet on something I can use…
Rob Bateman, Administrator Posted: 13 March 2013 02:18 PM Total Posts: 120 [ # 5 ] Hey owntheweb The problem is most likely the examples you are using are out of sync (in release terms) with the library you are using. As a suggestion, try using the latest source for library and examples from dev: https://github.com/away3d/away3d-core-fp11/tree/dev https://github.com/away3d/away3d-examples-fp11/tree/dev this should give you an error-free compilation
owntheweb, Jr. Member Posted: 13 March 2013 02:44 PM Total Posts: 32 [ # 6 ] That worked like magic! I was able to update my code quickly with the example. Mars is moving forward. :D http://www.flickr.com/photos/8139783@N08/8553873975/ Thank you muchly.
