Help for a lighting idiot? Software: Away3D 4.x

peytofu, Newbie Posted: 16 March 2013 04:00 PM Total Posts: 3 Pardon my format, but I don’t want to waste too much of your time. I am having alot of difficulty solving this issue. I am using away3D 4.0.9. Goals: —Create a scene with the perelith knight, a floor, and a light. (done) —All 3 are created in a class file(package) of their own. (done) —The light class returns a directional light that colors the scene & casts shadows. Issue: When I omit the light class & just create the light in the main/default class, everything works fine(both color & shadows). But when I try to use a light returned from my light class, I only get the default white lighting. Questions: —What is the correct structure of a custom class that will return a directional light? —Should the light be created in a function, and then modified with the custom light class…versus creating the light within the custom light class? Why? (Pardon my ignorance) I am trying to build the app this way because I want to force OOP as far as I can…because the app will be large when completed. Many thanks for your help!

peytofu, Newbie Posted: 16 March 2013 08:21 PM Total Posts: 3 [ # 2 ] Here is the rough breakdown: Here is the call from the main class: `_light = new RPTlights(); _view.scene.addChild(_light); _lightPicker = new StaticLightPicker([_light.setupLight()]);` Here is the custom light class: public class RPTlights extends ObjectContainer3D { public var _mylight : DirectionalLight; private var _lightPicker : StaticLightPicker; public function RPTlights() { super(); } public function setupLight():DirectionalLight { _mylight = new DirectionalLight(); _mylight.y = 300; _mylight.z = 0; _mylight.x = 0; //_light.lookAt( _mylight.diffuse = 0.7; _mylight.ambient = 0.1 _mylight.ambientColor = 0x00ff00; _mylight.specular = 0.25 _mylight.castsShadows = true; _mylight.name = "mylight"; addChild(_mylight); return _mylight; } } Then, I pass the light to the materials class like: `setMaterials(_light.setupLight());` Then, I handle the mats… but now this is throwing an error. public function setMaterials(_tmpLight:DirectionalLight):void{ floorMats(_tmpLight); playerMats(_tmpLight); } public function floorMats(_tmpLight:DirectionalLight):void { _floorMaterial = new TextureMaterial(Cast.bitmapTexture(FloorDiffuse)); _floorMaterial.lightPicker = _lightPicker; _floorMaterial.specular = .3; _floorMaterial.ambient = 1; _floorMaterial.repeat = true; _floorMaterial.shadowMethod = new NearShadowMapMethod(new FilteredShadowMapMethod(_tmpLight)); } public function playerMats(_tmpLight:DirectionalLight):void{ _playerMaterial = new TextureMaterial(Cast.bitmapTexture(PlayerDiffuse)); _playerMaterial.lightPicker = _lightPicker; _playerMaterial.specular = .3; _playerMaterial.ambient = 1; _playerMaterial.repeat = true; _playerMaterial.shadowMethod = new NearShadowMapMethod(new FilteredShadowMapMethod(_tmpLight)); }

When you receive this light in main, add the light to your picker and set it if not done yet.
peytofu, Newbie Posted: 17 March 2013 02:55 PM Total Posts: 3 [ # 4 ] Thanks for the help. I changed the light class to extend directionalLight and I also changed this line: setMaterials(_light.setupLight()); to be: setMaterials(_light._mylight); and now it appears to be behaving. Thanks again.
