Setting Up Objectives :: Wombat
-------------------------------------------------------------------------------

This tutorial follows on from the Scripted Exploders Tutorial.

The usage of the obj_dm.scr threw me for a while, but I managed to work out how to use this versatile script. I knew what had to be set, but could not get the game to set, via the [key][value] method. Part of the script, calls for the 'self.trigger_name' Variable. I worked out that this referred to the bomb, but when I set the bomb.trigger_name via the editor, and called the external routine and checked the print out the script outputs to the console (ingame). I could see that it was finding 'self.trigger_name' to be "NIL". I decided to change those variables required in the script, before initiating the bomb_thinker thread. Needless to say, is , if you set up the objectives, as I describe, and use my script method( feel free to use it ) then the objectives will play just like Omaha Beach or any other Objective map. To test the objective scripts. You need to comment out the 'level waitill roundstart' line by adding the '//'[comment command] ie "// level waitill roundstart" . This line tells the Multiplayer game to wait until two opposing members are in the game. Uncomment before distributing your map....

Now, onto the map editor specific stuff. This is actually easier to set up than the Exploder.

First, we need a Script_object, setting targetname as "Flak88obj1" and the model as "models/statweapons/flak88turret.tik". This is the gun. Add another script_object and give it the flak88base.tik model. This is the base of the gun and will be unaffected by the script.

Next we need another Script_object, set as targetname "bomb2", target as "Flak88obj1", and a model of "models/items/pulse_explosive.tik". Place it somewhere the player can access the bomb. Rotate using the angle[key] degrees[value] method.

Now we need to add the trigger_use. Set it as triggerable, targetname "trigger2". The trigger can be placed around the bomb.

It's all over bar the shouting. Save the map, and compile it. All the important stuff is done in the script. Onto that now.....Load it up in Notepad, and view it!

All the code does really, is set the parameters for the variables needed for the obj_dm.scr, before calling the script.

To access game entitys from the script, you prefix a $ sign to the targetname ie $bomb or $trigger2

You set up a bomb_thinker thread for every bomb (objective) you have in your map.

ie: $bomb thread global/obj_dm.scr::bomb_thinker
$bomb2 thread global/obj_dm.scr::bomb_thinker

Don't forget to modify the line level.targets_to_destroy = 2
to reflect the number of objectives.
Next the threads need to be set up for the scenarios. Allies or Axis win.

The first line says . If the bomb still lives , after the level times out, the axis win.

The second line says. Start a thread that checks for objectives all completed. Allies win.

The third and fourth lines start threads that wait for the bomb to be detonated and then outputs text to the screen.

Congratulations, you should be able to run the game, and enjoy the objectives you have set up. Next comes the hard bit, Mapping your Map. Good Luck and happy mapping.
