LlDialog

Template:Needs Translation/

函数名
Function: llDialog( key avatar, string message, list buttons, integer channel );
参数： avatar-在同一区域的关键人物头像UUID message-将显示在对话框中的消息 buttons-button列表标签 channel-输出聊天通道，任何整数值
返回值：在化身屏幕的右下角(Viewer 1.x的右上角)显示一个对话框，其中有消息和选择按钮，以及一个忽略按钮。它有许多用途，从简单的消息传递到复杂的菜单系统。

注意事项

注意事项 这个函数使脚本休眠1.0秒。 这个函数只打开一个对话框。然后，脚本还必须使用llListen在同一个通道上注册一个侦听器，并拥有一个侦听事件处理程序来接收响应。 没有办法通过脚本杀死一个对话框。 脚本无法检测用户是否单击了小["Ignore"]按钮(按下此按钮不会生成聊天)。 无法区分输入内容与同一用户的对话框和常规聊天内容。 预期响应可能不是其中一个按钮，这一点很重要。 在大多数情况下，侦听器将与llDialog位于相同的脚本中，但如果不是这样，侦听对象的根prim与生成prim的对话框之间的距离将成为一个因素。如果按下按钮时这个距离大于20米，则不会听到响应。看到#限制。 如果佩戴者移动距离听话者所在位置超过20米，此限制也会影响附件。看到#限制。 如果侦听器位于创建对话框的同一脚本中，则对话框按钮在simwide范围内被侦听。 默认情况下，Second Life查看器中的每个对象只能显示一个对话框。查看器中的ScriptDialogLimitations调试设置可以覆盖这一点。 对话框响应(生成的聊天)在根prim的全局位置有它的世界位置。它可以在距离该位置20米内生成侦听事件。 对象中子prim的监听位置要么在子prim的位置，要么在根prim的位置 参见bugtrace JIRA SCR-43

示例

示例1 // When the prim is touched, give the toucher the option of killing the prim. integer gListener; // Identity of the listener associated with the dialog, so we can clean up when not needed default { touch_start(integer total_number) { // Kill off any outstanding listener, to avoid any chance of multiple listeners being active llListenRemove(gListener); // get the UUID of the person touching this prim key user = llDetectedKey(0); // Listen to any reply from that user only, and only on the same channel to be used by llDialog // It's best to set up the listener before issuing the dialog gListener = llListen(-99, "", user, ""); // Send a dialog to that person. We'll use a fixed negative channel number for simplicity llDialog(user, "\nDo you wish this prim to die?", ["Yes", "No" ] , -99); // Start a one-minute timer, after which we will stop listening for responses llSetTimerEvent(60.0); } listen(integer chan, string name, key id, string msg) { // If the user clicked the "Yes" button, kill this prim. if (msg == "Yes") llDie(); // The user did not click "Yes" ... // Make the timer fire immediately, to do clean-up actions llSetTimerEvent(0.1); } timer() { // Stop listening. It's wise to do this to reduce lag llListenRemove(gListener); // Stop the timer now that its job is done llSetTimerEvent(0.0);// you can use 0 as well to save memory } } 示例2 string mainMenuDialog = "\nWhich settings would you like to access?\nClick \"Close\" to close the menu.\n\nYou are here:\nMainmenu"; list mainMenuButtons = ["sub 01", "sub 02", "Close"]; string subMenu_01_Dialog = "\nClick \"Close\" to close the menu.\nClick \"-Main-\" to return to the main menu.\n\nYou are here:\nMainmenu > sub 01"; list subMenu_01_Buttons = ["action 01a", "action 01b", "Close", "-Main-"]; string subMenu_02_Dialog = "\nClick \"Close\" to close the menu.\nClick \"-Main-\" to return to the main menu.\n\nYou are here:\nMainmenu > sub 02"; list subMenu_02_Buttons = ["action 02a", "action 02b", "Close", "-Main-"]; integer dialogChannel; integer dialogHandle; open_menu(key inputKey, string inputString, list inputList) { dialogChannel = (integer)llFrand(DEBUG_CHANNEL)*-1; dialogHandle = llListen(dialogChannel, "", inputKey, ""); llDialog(inputKey, inputString, inputList, dialogChannel); llSetTimerEvent(30.0); } close_menu() { llSetTimerEvent(0.0);// you can use 0 as well to save memory llListenRemove(dialogHandle); } default { on_rez(integer start_param) { llResetScript(); } touch_start(integer total_number) { key id = llDetectedKey(0); // Ensure any outstanding listener is removed before creating a new one close_menu(); open_menu(id, mainMenuDialog, mainMenuButtons); } listen(integer channel, string name, key id, string message) { if(channel != dialogChannel) return; close_menu(); if(message == "-Main-") open_menu(id, mainMenuDialog, mainMenuButtons); else if(message == "sub 01") open_menu(id, subMenu_01_Dialog, subMenu_01_Buttons); else if(message == "sub 02") open_menu(id, subMenu_02_Dialog, subMenu_02_Buttons); else if (message == "action 01a") { //do something open_menu(id, subMenu_01_Dialog, subMenu_01_Buttons); } else if (message == "action 01b") { //do something else //maybe not re-open the menu for this option? //open_menu(id, subMenu_01_Dialog, subMenu_01_Buttons); } else if (message == "action 02a") { //do something open_menu(id, subMenu_02_Dialog, subMenu_02_Buttons); } else if (message == "action 02b") { //do something else open_menu(id, subMenu_02_Dialog, subMenu_02_Buttons); } } timer() { close_menu(); } }
