Dialog boxes!

[FireCross88]

How do I create a popup dialog box in irrlicht when I've reached a certain position?

Like in Resident Evil, when you reach an item and press X, a dialog box comes up.

Thanks!

No one knows how? This is a really important aspect for my school project!

Thanks!

Write yourself a function to check if the players X, Y and Z coordinates are within a certain range (for example, the target position's X, Y and Z +- 10 units or something like that) and if the function returns true, use Irrlichts GUI stuff to make a message show up on screen. Hope that helps

Make a bounding box [core::aabbox3df] that describes the position that you want the 'trigger' to be at. In your main game loop, check to see if the player scene node absolute position is inside the box. If it is, set a flag that indicates the 'trigger' has been used, and then create your message box. Something like this...

Code: Select all

core::aabbox3df box(100, 100, 100, 110, 110, 110);
bool triggered = false;

while (device->run())
{
  if (driver->beginScene(...))
  {
    smgr->drawAll();

    driver->endScene();
  }

  if (!triggered && box.isPointInside( player->getAbsolutePosition() )
  {
    triggered = true;

    // create dialog or whatever
  }
}

Once you get that working, you can abstract it out a little bit. You could make a trigger interface that knows how to check that some condition is met, sets an internal 'triggered' flag and calls a function or does some other arbitrary thing. Then you can read these triggers from a configuration file and add them to a list of triggers. Every few ticks you can evaluate a few of the triggers...

Sorry, maybe I should've been more specific.

I already know how to create the bounding box and trigger stuff, etc.

What I don't know how to do is to invoke Irrlicht's GUI or whatever to ACTUALLY create the dialog box, so I need detailed info for that.

Thanks!

have a look at tutorial #05.UserInterface, it shows you how to create windows and other gui stuff...
