在Blender 2.92中使用IntProperties时，会导致插件崩溃。解决方法是使用FloatProperties或EnumProperties代替IntProperties。

以下是使用FloatProperties的示例代码：

import bpy

class MyProperties(bpy.types.PropertyGroup):
    my_int: bpy.props.FloatProperty(
        name="My Int",
        default=0
    )

class MyOperator(bpy.types.Operator):
    bl_idname = "object.my_operator"
    bl_label = "My Operator"

    def execute(self, context):
        props = context.scene.my_properties
        print(props.my_int)
        return {'FINISHED'}

class MyPanel(bpy.types.Panel):
    bl_idname = "OBJECT_PT_my_panel"
    bl_label = "My Panel"
    bl_space_type = "VIEW_3D"
    bl_region_type = "UI"
    bl_category = "My Addon"

    def draw(self, context):
        props = context.scene.my_properties
        self.layout.prop(props, "my_int")
        self.layout.operator("object.my_operator", text="Print Int")

classes = (
    MyProperties,
    MyOperator,
    MyPanel
)

def register():
    for cls in classes:
        bpy.utils.register_class(cls)
    bpy.types.Scene.my_properties = bpy.props.PointerProperty(type=MyProperties)

def unregister():
    del bpy.types.Scene.my_properties
    for cls in classes:
        bpy.utils.unregister_class(cls)

if __name__ == "__main__":
    register()

这是使用EnumProperties的示例代码：

import bpy

class MyEnumChoices:
    VALUES = (
        ("A", "Option A", ""),
        ("B", "Option B", ""),
        ("C", "Option C", "")
    )

class MyProperties(bpy.types.PropertyGroup):
    my_int: bpy.props.EnumProperty(
        name="My Int",
        items=MyEnumChoices.VALUES,
        default="A"
    )

class MyOperator(bpy.types.Operator):
    bl_idname = "object.my_operator"
    bl_label = "My Operator"

    def execute(self, context):
        props = context.scene.my_properties
        print(props.my_int)
        return {'FINISHED'}

class MyPanel(bpy.types.Panel):
    bl_idname = "OBJECT_PT_my_panel"
    bl_label = "My Panel"
    bl_space_type = "VIEW_3D"
    bl_region_type = "UI"
    bl_category = "My Addon"

    def draw(self, context):
        props = context.scene.my_properties
        self.layout.prop(props, "my_int")
        self.layout.operator("object.my_operator", text="Print Int")

classes = (
    MyProperties,
    MyOperator,
    My
