AngelScript 2.20.1 is released

Andreas Jonsson · 2011-03-21T03:00:52

This version has been mostly about internal improvements where the compiler and VM are now allocating local variables of registered value types on the stack instead of on the heap. If your scripts you a lot of those you should see a pretty good performance increase, as there will be less dynamic memory allocations. There was a bug fix to the debug methods in the asIScriptContext. The call stack index used to inspect functions higher up on the call stack was inverted, so the methods were actually returning the information of the wrong function. If you are using these methods you may need to adjust your code when picking up this version. Regards,Andreas

Using r779, there still seems to be problems, sorry to bother you. I have a quite large script code base and I would like to avoid rewriting it as much as possible.

This line gives "Null pointer access" :

Vector2 targetAnchor = _cameraDef[Level.cameraID - 1]._targetCameraWeight <= 0.0f ? Vector2(Level.camera.lookAt) : _cameraDef[Level.cameraID - 1]._targetCameraAncor;

(Also, the cast to Vector2 is there in the first place to avoid "Both sides of the expression must be of the same type".)

However, this equivalent code is fine (when placed at the same line in the same file) :

Vector2 targetAnchor;

if (_cameraDef[Level.cameraID - 1]._targetCameraWeight <= 0.0f)

{

	targetAnchor = Vector2(Level.camera.lookAt);

}

else

{

	targetAnchor = _cameraDef[Level.cameraID - 1]._targetCameraAncor;

}

I'll look into it.

Aparently my test cases aren't covering enough situations to catch these problems. But it's good that you're able to isolate the problems so that I can fix them quickly and make them part of my test cases for future changes.

It does not seem to crash anymore but all my scripted events are not called anymore which is a little bit annoying. I'll get back when I have more information.

Thanks for all the fixes so far, you've been really helpful

EDIT : I forgot to say that my events are called on PC but not on PS3 actually, they were fine with 2.20.0

EDIT : Okay nevermind, mistake from my side here, you can't declare parameters as passed by value on PS3, I forgot that some days ago when I added some script functions, everything seems to work perfectly. Thanks for everything

I just found a small bug with the std::string addon :

string s = "hello";



for (int i = 0; i < 10; ++i)

{

	print(s + i + "\n");

}

This outputs :

hello0

hello01

hello012

hello0123

hello01234

hello012345

hello0123456

hello01234567

hello012345678

hello0123456789

Hello,

It's me again and I have a new bug. We compile on a new platform which is Xbox 360 and it crashes.

Here is the as_content.cpp (line 2371) part :

	case asBC_WRTV1:

		// The pointer in the register points to a byte, and *(l_fp - offset) too

		**(asBYTE**)&regs.valueRegister = *(asBYTE*)(l_fp - asBC_SWORDARG0(l_bc));

		l_bc++;

		break;

The script part :

class ArrayOf

{

	bool[] _boolList;

	int _numOfStockedObject;

	ArrayOf(int arraySizeMax)

	{

		_boolList.resize(arraySizeMax);

		_numOfStockedObject = 0;

		for(int i = 0; i < arraySizeMax; ++i)

		{

			_boolList = false;

		}

	}

}

It's the line inside the "for" that seems to crash (this is the last one in the line callback).

The compiler options : AS_XBOX360 AS_XENON (from asGetLibraryOptions).

EDIT : I use revision 781.

Remi Gillig.

It's probably due to the XBOX 360 being a big-endian CPU.

Would it be possible for you to confirm whether the problem happens when compiling with AS_MAX_PORTABILITY, i.e. without using the native calling conventions? That would help narrow determine whether problem is in the as_callfunc_xenon.cpp or not.
