AngelScript 1.10.0 FINAL (2004/11/02)

Andreas Jonsson · 2004-11-19T12:17:22

This is the largest update ever made in one release, during the AngelScript history. A very shortened list of updates that were made is: Further optimized the VM with perhaps 1.5x average performance improvement Quite a few bug fixes A new boolean operator, xor, was added The library interface was improved, especially functions that returned strings ExecuteStep() now works as before (if the correct compile time flags are set) ExecuteString() has gotten a much needed overhaul. It's now possible to call it recursively, and also from multiple threads at the same time. The much awaited native support for arrays have finally been implemented. Now script writers can enjoy the full power of arrays in their functions. Application writers can easily register the exact array objects that they need for their functions, which makes the interaction very easy. Basic support for multithreading has been added, though it can be disabled at compile time for those who need the extra performance. Those are the most important points. You can read the complete list on the AngelScript site. Enjoy!

Hmm...I can't really chop my code up to provide a simple example, but I can describe the situation. I have an array of pointers to a class with properties and methods. In a loop i call a method that returns new instances

MyClass *[] c(5);int i;for(i=0;i<5;++i) {  c=RegisteredAllocatorForMyClass();  c->RegisteredDoStuff(45.0f,1.0f);}

And I get two problems:
the first, execution dies inside the for loop (but where, i'm not sure yet)
the second, if I change to MyClass [] and get rid of the allocation then I get No matching signatures to 'RegisteredDoStuff(const float, const float)'. I registered as non-const. If I change the registartion and internal methods to const I still get the error.

Also note that if I allocate like this

MyClass *ptr=RegisteredAllocatorForMyClass();

It does allocate (but I still get the No Matching signatures problem). That's all I've been able to figure out so far.

Ok, that information might be enough for me to find the problem. I'll give it a try and let you know.

But before that I'd like to know if you noticed the post by Licu about the pointer related bug in AS 1.10? If you didn't then this may actually be what is causing your problems.

You'll find the bug fix for the -> operator in that thread.

I added the fix for the -> operator and now I get an assert about

instr->StackSize == StackSize

There seems to be a problem with arrays of pointers. I've written a test case using your example and it gives errors it shouldn't.

I'm looking into this right now, but I might not be able to fix it until Sunday.

Well that throws my schedule off a couple of days, but I'll find things to work on in the meantime. I wish you godspeed with whatever you're doing :)

The problem I had found was related to me using integer to index the arrays. Once I change the type of n to uint it worked fine. (NOTE: I will improve the implicit casting rules for the next version)

void Test()                                {                                            class1*[] c(5);                            uint i;                                    for( i = 0; i < 5; ++i )                   {                                            c = class1Factory();                    c->function();                        }                                        }

This compiles and executes without problem (except that the compiler reports c as uninitialized, which is a bug but not a critical one).

The assert(instr->StackSize == StackSize) is probably related to the first problem you mentioned. It seems the compiler is trying to dereference a registered object even though it shouldn't.

This might be related to how you have registered your type. Can you show me how you registered the type in question? The one that was being dereferenced?

I meant to type uint. Sorry.

  asEngine->RegisterObjectType("ObjectInstance", sizeof(ObjectInstance), asOBJ_CLASS);  asEngine->RegisterGlobalFunction("ObjectInstance *CreateObjectInstance(ObjectType *type)",asFUNCTION(::CreateObjectInstance),asCALL_CDECL);  asEngine->RegisterGlobalFunction("void ReleaseObjectInstance(ObjectInstance *)",asFUNCTION(::ReleaseObjectInstance),asCALL_CDECL);  asEngine->RegisterObjectMethod("ObjectInstance","GfxTexture *GetTexture()",asMETHOD(ObjectInstance, GetTexture), asCALL_THISCALL);  asEngine->RegisterObjectMethod("ObjectInstance","void SetTexture(GfxTexture *)",asMETHOD(ObjectInstance, SetTexture), asCALL_THISCALL);  asEngine->RegisterObjectMethod("ObjectInstance","GfxMesh *GetMesh()",asMETHOD(ObjectInstance, GetMesh), asCALL_THISCALL);  asEngine->RegisterObjectMethod("ObjectInstance","void SetMesh(GfxMesh *)",asMETHOD(ObjectInstance, SetMesh), asCALL_THISCALL);  asEngine->RegisterObjectMethod("ObjectInstance","bool ComesBefore(ObjectInstance *)",asMETHOD(ObjectInstance, ComesBefore), asCALL_THISCALL);  asEngine->RegisterObjectMethod("ObjectInstance","ObjectType *GetType()",asMETHOD(ObjectInstance, GetType), asCALL_THISCALL);  asEngine->RegisterObjectMethod("ObjectInstance","void SetPosition(float,float)",asMETHOD(ObjectInstance, SetPosition), asCALL_THISCALL);  asEngine->RegisterObjectMethod("ObjectInstance","void GetPosition(float&,float&)",asMETHOD(ObjectInstance, GetPosition), asCALL_THISCALL);  asEngine->RegisterObjectMethod("ObjectInstance","void SetVelocity(float,float)",asMETHOD(ObjectInstance, SetVelocity), asCALL_THISCALL);  asEngine->RegisterObjectMethod("ObjectInstance","void SetAngle(float)",asMETHOD(ObjectInstance, SetAngle), asCALL_THISCALL);  asEngine->RegisterObjectMethod("ObjectInstance","void SetAngularVelocity(float)",asMETHOD(ObjectInstance, SetAngularVelocity), asCALL_THISCALL);  asEngine->RegisterObjectMethod("ObjectInstance","void AssignPhysics(ObjectPhysicsDescription &opd)",asMETHOD(ObjectInstance, AssignPhysics),asCALL_THISCALL);  asEngine->RegisterObjectMethod("ObjectInstance","void SetName(string &)",asMETHOD(ObjectInstance, SetName), asCALL_THISCALL);  asEngine->RegisterObjectMethod("ObjectInstance","void SetStack(int pos,float v)",asMETHOD(ObjectInstance, SetStack), asCALL_THISCALL);  asEngine->RegisterObjectMethod("ObjectInstance","float GetStack(int pos)",asMETHOD(ObjectInstance, GetStack), asCALL_THISCALL);  asEngine->RegisterObjectMethod("ObjectInstance","void SetImmaterial(bool state)",asMETHOD(ObjectInstance, SetImmaterial), asCALL_THISCALL);  asEngine->RegisterObjectMethod("ObjectInstance","bool GetImmaterial()",asMETHOD(ObjectInstance, GetImmaterial), asCALL_THISCALL);

Hmm, I can't see anything wrong with the way you registered the object.

I think I'll need to know what script function it is that is causing the assert failure. Would it be possible for you to find this? Simply comment out the script functions one by one until you find the one that fails compiling.

In the meanwhile I will look through the library code for possible causes.

ObjectInstance *[] instanceArray(5);uint i=0;instanceArray=ObtainObjectInstance(type);

is causing the problem.

Unfortunately I don't seem to be able to reproduce the problem. Everything seems to work fine for me.

I will continue to search but without being able to reproduce the problem myself it is highly unlikely I'll find it.
