Conditional Firing

[catfighter]

How would I set conditions on firing a weapon? For example, unless you have a certain item in your cargo hold, the weapon won't work or a weapon shoots a different kind of projectile if you're in a nebula or dust cloud. Also, can this extend to other devices as well? Maybe a shield that get's bonuses based on environment. I read that unlimited-fire weapons intake material from the environment and I was thinking about making this a bit more realistic in terms of what comes out the other end of the gun barrel.

For the first(ish) question, set the weapon to use some item as ammo. The weapon will now be unable to fire unless you have that item on your ship. Then set the weapon to add one unit of that item to your ship whenever it is fired (see attached code) so that you won't actually run out of the item. The main flaw with this method is that unless you can find a function to retrieve the itemtype of the currently selected ammo, the ammo has to be hard-coded in and the weapon will therefore be limited to one type of ammo.

Code: Select all

<Events>
	<OnFireWeapon>
		 (objAddItem gplayerShip (itmCreate 0x4001 1) 1)
	</OnFireWeapon>
</Events>

For the second part about having a weapon/device operate differently in a nebula, as far as I know there is no way to directly tell if a ship is inside a nebula or not. I believe I read in a thread somewhere that being in a nebula now gives your ship a +2 bonus to its stealth rating and a -4 penalty to its perception rating. In the thread I posted about the DRADIS device that will be included in the next version of my Cabbage Corp mod I included the code necessary to retrieve the current perception value of a ship. Unfortunately this function only works for npc ships, but it could theoretically be used to determine if a ship is in a nebula by comparing its current perception value to some baseline value.

You can try sysGetEnvironment in the funclist http://forums.kronosaur.com/viewtopic.php?f=8&t=6926 .
This should return &evnebula; or something similar when in nebula.
