steam_ugc_start_item_update(consumer_app_id, published_file_id);

Returns: Handle

描述

This function must be called before adding or updating information on a UGC item. You need to supply the unique App ID for your game on Steam, along with the unique published file ID that was returned for the item when you created it using the function steam_ugc_create_item. The function will return a unique update handle for the item, which you can then use in the UGC item functions to update (or add) information for uploading.

例如：

var app_id = steam_get_app_id();
var updateHandle = steam_ugc_start_item_update(app_id, global.Publish_ID);
steam_ugc_set_item_title(updateHandle, "My workshop item(3)!");
steam_ugc_set_item_description( updateHandle, "testing workshop...");
steam_ugc_set_item_visibility(updateHandle, ugc_visibility_public);
var tagArray;
tagArray[0] = "Test";
tagArray[1] = "New";
steam_ugc_set_item_tags(updateHandle, tagArray);
steam_ugc_set_item_preview(updateHandle, "promo.jpg");
steam_ugc_set_item_content(updateHandle, "WorkshopContent1");
requestId = steam_ugc_submit_item_update(updateHandle, "Version 1.2");

The above code gets the game ID, then uses that along with a previously stored published file ID to generate an update handle for the item. This handle is then used to update various peices of information before the update is pushed to the Workshop servers.
