# ChatMessage.gd - 聊天消息气泡组件
|

# ============================================================================
|

# 显示单条聊天消息的 UI 组件
|
||
#
|
||
# 核心职责:
|
||
# - 显示消息发送者、内容、时间戳
|
||
# - 区分自己和他人的消息样式
|
||
# - 自动格式化时间戳
|
||
#
|
||
# 使用方式:
|
||
# var message := chat_message_scene.instantiate()
|
||
# message.set_message("PlayerName", "Hello!", timestamp, false)
|
||
#
|
||
# 注意事项:
|
||
# - 使用 @onready 缓存节点引用
|
||
# - 最大宽度限制为 400 像素
