c++ - 3dsmax SDK c++ bonesdef.h

Question

这是我的代码，如果我把它放在 BonesDef 项目中就可以完美地工作:

#include "mods.h"
#include "bonesdef.h"
#include <maxscript/macros/define_instantiation_functions.h>
#include "modstack.h"

Modifier* FindSkinModifier(INode* nodePtr)
{
    Object* ObjectPtr = nodePtr->GetObjectRef();
    if (!ObjectPtr) return NULL;
    while (ObjectPtr && ObjectPtr->SuperClassID() == GEN_DERIVOB_CLASS_ID)
    {
        IDerivedObject *DerivedObjectPtr = (IDerivedObject *)(ObjectPtr);
        int ModStackIndex = 0;
        while (ModStackIndex < DerivedObjectPtr->NumModifiers())
        {
            Modifier* ModifierPtr = DerivedObjectPtr->GetModifier(ModStackIndex);
            if (ModifierPtr->ClassID() == Class_ID(SKIN_CLASSID)) 
            {
                return ModifierPtr;
            }
            ModStackIndex++;
        }
        ObjectPtr = DerivedObjectPtr->GetObjRef();
    }
    return NULL;
}

void RecursiveRemoveUnusedBones(INode* node)
{
    Modifier* skin = FindSkinModifier(node);
    if (skin)
    {
        ISkin* iskin = (ISkin*)skin->GetInterface(I_SKIN);
        BonesDefMod* bmod = (BonesDefMod*)iskin;
        ISkinContextData* skinData = iskin->GetContextInterface(node);
        BitArray usedbones = BitArray(iskin->GetNumBones());
        for (int i = 0; i < skinData->GetNumPoints(); i++)
        {
            for (int j = 0; j < skinData->GetNumAssignedBones(i); j++)
            {
                int boneIndex = skinData->GetAssignedBone(i, j);
                float boneWeight = skinData->GetBoneWeight(i, j);
                if (boneWeight > 0) usedbones.Set(boneIndex);
            }
        }
        for (int i = usedbones.GetSize(); i >= 0; i--)
        {
            if (usedbones[i] != 1) bmod->RemoveBone(i);
        }
    }

    for (int i = 0; i < node->NumberOfChildren(); ++i)
    {
        RecursiveRemoveUnusedBones(node->GetChildNode(i));
    }
}

def_visible_primitive(RemoveUnusedBones, "RemoveUnusedBones");
Value* RemoveUnusedBones_cf(Value **arg_list, int count)
{
    RecursiveRemoveUnusedBones(GetCOREInterface()->GetRootNode());
    return &ok;
}

但问题是，如果我将这段代码放在 BonesDef 项目之外的项目中，我会遇到几个错误:

Severity    Code    Description    Project    File    Line    Suppression State
Error    LNK2001    unresolved external symbol "public: void __cdecl BonesDefMod::RemoveBone(int)" (?RemoveBone@BonesDefMod@@QEAAXH@Z)    SamplePlugin    C:\Users\Mehdi\Documents\Visual Studio 2015\Projects\SamplePlugin\Source.obj    1

这是我的附加内容:

F:\Software\3dsMax\SDK\3ds Max 2018 SDK\maxsdk\obj\x64\Release\bonesdef\
F:\Software\3dsMax\SDK\3ds Max 2018 SDK\maxsdk\include\XRef
F:\Software\3dsMax\SDK\3ds Max 2018 SDK\maxsdk\samples\modifiers\bonesdef
F:\Software\3dsMax\SDK\3ds Max 2018 SDK\maxsdk\include
%(AdditionalIncludeDirectories)

和图书馆:

F:\Software\3dsMax\SDK\3ds Max 2018 SDK\maxsdk\lib\x64\Release
%(AdditionalLibraryDirectories)

但始终无法构建。我的问题是如何配置项目以便使用(调用)BonesDef(Skin) 函数？

Answer 1

我终于弄明白了如何创建一个独立项目并包含 BonesDef 函数!我们应该遵循以下步骤:

1. 包含 BonesDef.h。
2. 创建 BonesDef (.lib) 的静态库。
3. 将该库添加到项目设置/附加库。
4. 从 BonesDef 项目/Additional Dependency 复制依赖列表并将其附加到我们的项目。
5. 将 BonesDef.lib 附加到 Additional Dependency 选项。
