我在Blender(2.6)中有一个带有装配动画的模型.我将它导出到FBX并将其导入XNA.我知道如何在屏幕上绘制它但是如何运行动画(例如称为“运行”)？

谢谢！

解决方法:

你可以使用微软的SkinnedModelSample.确保在属性框中将fbx文件的ContentProcessor属性设置为SkinnedModelProcessor,然后您可以执行(需要优化)：

主要游戏类：

AnimationPlayer player;// This calculates the Matrices of the animation
AnimationClip clip;// This contains the keyframes of the animation
SkinningData skin;// This contains all the skinning data
Model model;// The actual model

LoadContent方法：

model = Content.Load<Model>("path_to_model");
skin = model.Tag as SkinningData;// The SkinnedModelProcessor puts skinning data in the Tag property

player = new AnimationPlayer(skin);
clip = skin.AnimationClips["run"];// The name of the animation

player.StartClip(clip);

绘制方法：

Matrix[] bones = player.GetSkinTransforms();

// Compute camera matrices.
Matrix view = Matrix.CreateLookAt(new Vector3(0, 0, -30), // Change the last number according to the size of your model
                                          new Vector3(0, 0, 0), Vector3.Up);

Matrix projection = Matrix.CreatePerspectiveFieldOfView(MathHelper.PiOver4,
                                                        device.Viewport.AspectRatio,
                                                        1,
                                                        10000);

// Render the skinned mesh.
foreach (ModelMesh mesh in model.Meshes)
{
    foreach (SkinnedEffect effect in mesh.Effects)
    {
        effect.SetBoneTransforms(bones);

        effect.View = view;
        effect.Projection = projection;

        effect.EnableDefaultLighting();

        effect.SpecularColor = new Vector3(0.25f);
        effect.SpecularPower = 16;
    }

    mesh.Draw();
}
