Passing struct to script
Author
Hi
I am trying to do this
test.as
void func(obj &testObj)
{
testObj.a = 5;
}
I am using the testexecutescript.cpp from the 2.0.0 SDK as base for this.
Load is ok
compile fails

A suggestion would be to add explaining code to the register class page from the documentation on the angelscript site since I have a hard time figuring out what to pass.
There are quite a few examples with angelscript too. But none that I have found that show passing a struct or class to the script and then call a method and alter a property. I guess there should be one of those examples so if someone could tell me which example I should look at I will try to take it from there :)

It would help if you tell me what the error codes/messages that you receive are.
You've forgotten to specify the in/out/inout for the parameter reference in the script. This would cause the build to fail.
In the application code you don't show how you register the testObj structure, also from your what you show you don't call ctx->Prepare() before setting the argument. Otherwise you are correct in the way you pass the argument to the script function.

Yes, the documentation needs to improve a lot. I'll try to add the code samples as you mentioned.
The test applications that come with the SDK aren't very good for teaching, as they take a few shortcuts, especially in error checking etc. I only use them for verifying that everything works.
I need to write some dedicated samples/tutorials to do teach how to use the library. I think I have a good idea for a simple sample that will show much of what is needed.
In the meantime I suggest you take a look at test_vector3.cpp in the test_feature project. It shows how to register a simple structure, and how to pass this to the script functions.

Ah that seems to be an excellent example of what I want to achieve.
I can probably get that working.
Which is the best example for getting class methods called? I guess you are not writing the new class tutorial tonight :)

You might look at these:
test_object.cpp
teststdstring.cpp / stdstring.cpp
testvirtualmethod.cpp
I'm not sure when I will get the time to write the sample. But I will try to do it as soon as possible, as I know many people would benefit from it.

I hope you get the time.
It looks like the perfect thing for my RPG that I just have started to work on.
