Mission Info

Manages mission info dialogues and activity accept popups in the UI.

Overview

ui_missionInfo handles opening/closing mission information dialogues and activity accept screens. It stores button callback tables, dispatches actions by name or index, and pushes/pops the MissionUIActionMap for input handling.

Internals

State

• M.buttonsTable - Array of {action, cmd} for mission dialogues, or indexed callbacks for activities.
• M.openState - Tracks "opened" / "closed" for onMissionInfoChangedState hook.

openDialogue Flow

1. Optionally pushes MissionUIActionMap (unless content.actionMap == false).
2. Stores content.buttons in M.buttonsTable.
3. Triggers MissionInfoUpdate with content.
4. Plays event:>UI>Missions>Info_Open.

openActivityAcceptDialogue Flow

2. Fires onActivityAcceptUpdate extension hook and ActivityAcceptUpdate guihook.
3. Updates M.openState and fires onMissionInfoChangedState.

closeDialogue Flow

1. Pops MissionUIActionMap.
2. Clears buttonsTable.
3. Triggers MissionInfoUpdate(nil) and ActivityAcceptClose(nil).
4. Updates M.openState to "closed".

How It Works

1. A mission or activity calls openDialogue or openActivityAcceptDialogue with content.
2. The UI renders the dialogue; user clicks a button.
3. UI calls performAction(actionName) which finds the matching button and runs loadstring(button.cmd)().
4. When dismissed, closeDialogue cleans up input maps and triggers close events.

Lua Examples

-- Open a simple mission info dialogue
extensions.ui_missionInfo.openDialogue({
  title = "Delivery Mission",
  text = "Deliver the package to the destination.",
  buttons = {
    { action = "accept", cmd = "print('accepted')" },
    { action = "decline", cmd = "print('declined')" },
  }
})

-- Close the dialogue
extensions.ui_missionInfo.closeDialogue()
