If object A has a label, the label stores data of type Vec3.
I can't get the value of this label correctly in DLL. I try to cast the type and it looks fine, but I get an error during the edit phase.
Maybe I should know how to type cast in a DLL.How can I cast directly while writing a DLL ?

Use the Vec3 constructor that takes 3 parameters.
Variant loc = A->labels["LOC"]->value; Vec3 oldLOC = Vec3(loc[1], loc[2], loc[3]);
Since an Array doesn't have x, y, or z properties, the constructor that it is trying to use is returning compiler errors.
Thank you This reply solved my problem very well. But then I had a problem. How do I give an object a label of type Vec3? I tried something but it didn't work.
Variant loc = A->labels["LOC"]->value; Vec3 oldLOC = Vec3(loc[1], loc[2], loc[3]); Vec3 newLOC = oldLOC.project(station1, station2); Array arrayLoc = Array(); arrayLoc[1] = newLOC.x; arrayLoc[2] = newLOC.y; arrayLoc[3] = newLOC.z; A->labels["LOC"]->value = arrayLoc;
Vec3 is not a Datatype for a label. You can only cast it as an array. If you need a Vec3 variable you have to cast it from your array.
Maybe you should try to test your coding in FlexSim directly before you implement it a DLL. So you can see what FlexSim supports.
You can only use objectAs() when you are casting the data on a treenode to a SimpleDataType*, a CouplingDataType* or an ObjectDataType*, or a derivative of those classes.
Vec3 isn't one of those classes. You can, however, cast it as an Array (which can be stored on a node because it is a Variant), and then cast the Array back to a Vec3:
// You can explicitely cast a Variant as an array. Then the compiler should be able to implicitly cast the array to a Vec3 Vec3 oldLoc = (Array)A->labels["LOC"]->value;
Hi,Jordan.I tried to use your code, but I still got an error when compiling it.
Jordan's answer presumes you are using the Module SDK to build your DLL with the latest FlexSim header files.
If you are using the DLL Maker instead of the Module SDK, then you won't have access to all of those properties and methods.
Hi,Phil. I am using the Module SDK to build your DLL,but not with the latest FlexSim header files .Does that matter ?
