![]() I'm compiling in Visual Studio with /W4 and addressing all warnings as they come up. This way, I can write GetScalar(camera.Roll, evaluateInfo) or GetScalar(camera.Visibility, evaluateInfo) instead of having a multiple-line mess of uninitialized buffers and casts littering my code. Prop.GetData(&data, sizeof(data), evaluateInfo) Inline DataT GetScalar(FBProperty& prop, FBEvaluateInfo* evaluateInfo) Here's a utility function I wrote to evaluate the value of a scalar property: template In order to access a MotionBuilder property's value, you read it into a double variable, regardless of what sort of data type it actually represents. All values are either truthy or falsy, but most values are loosely equal to neither true nor false.I'm working with the API for an application called MotionBuilder. Truthy values are even more unlikely to be loosely equal to true. Objects are always truthy, but their primitive representation may be loosely equal to false."0" (and other string literals that are not "" but get coerced to 0) is truthy but loosely equal to false.NaN, undefined, and null are falsy but not loosely equal to false. ![]() In general, falsiness and = false differ in the following cases: Comparing strings and booleans results in both being converted to numbers, and they both become 0, so = false is true. However, when comparing with false, which is a primitive, is also converted to a primitive, which is "" via (). ![]() It's truthy, because all objects are truthy. is truthy, but it's also loosely equal to false. log ( " is truthy" ) } if ( = false ) // is truthy // = false Object.prototype._lookupSetter_() Deprecated.Object.prototype._lookupGetter_() Deprecated. ![]()
