【界面UI】聊天气泡与自定义表情的实现

---聊天消息的气泡渲染
function Bubble.render(actor, text)
    local bubble = GUI:Image_Create(sceneLayer, "bubble_" .. actor:GetUserId(), actor.x, actor.y - 60, "bubble_bg.png")
    local rich = GUI:RichText_Create(bubble, "msg", 12, 8, parseEmoji(text), 200, 13, "#FFFFFF")
    QF_Delay(6000, function()
        bubble:removeFromParent()
    end)
    return bubble
end

-- 表情标记解析：[名字] 换成图片元素
function parseEmoji(text)
    local parts = SL:Split(text, "%[")
    local out = ""
    for i, part in ipairs(parts) do
        local close = string.find(part, "]")
        if i > 1 and close then
            local emojiName = string.sub(part, 1, close - 1)
            if EMOJI_TABLE[emojiName] then
                out = out .. "#<img=" .. EMOJI_TABLE[emojiName] .. ">#" .. string.sub(part, close + 1)
            else
                out = out .. part
            end
        elseif i == 1 then
            out = part
        end
    end
    return out
end
