AddAction once out of water, then action deleted from list?

[HateDread 13]

Hey guys,

Trying to get some sort of diver weapon storage working, but I can't figure out how to efficiently add some sort of condition that only adds an action to the menu when the player reaches the shore. I want it to disappear once activated, to be replaced by a counter action (i.e. 'retrieve diving gear' when the first one was 'store diving gear').

Just having trouble conceptualizing how to pass back some of the stuff through an execVM to the unit (as I was calling the diver's .sqf in the init field, but that might not be preferable?)

Thanks in advance!

You probably didnt know but you can set a condition that defines when an action is shown/available.

That way you dont have to mess around with adding, removing and possibly readding the action. Much less hassle. :)

Do it like this and the action will only show up when underwater:

act = this addAction["youractionname","thescripttocall.sqf","",1,false,true,"underwater player"];

You could use something similar to only make the action show up when a certain item is in the player-iventory.

More details here:

Number = unitName addAction [title, filename, (arguments, priority, showWindow, hideOnUse, shortcut, condition, positionInModel, radius, radiusView, showIn3D, available, textDefault, textToolTip)]

I've tried "!(underwater player)", but the action is still available no matter what. I'd prefer it to not even be available while on top of the water... the player has to be on solid ground. I tried getposASL, but I screwed that up too.

Can I pass something back into the init space that forms part of the condition for the opposite action? So either the variable passed back into the unit init space is a yes for action 1, or a yes for action 2, and so the appropriate action is shown in the menu. But I feel that this would be inefficient and messy, and I'm not sure if the init space can be changed after game start? (Probably... hence the name).

You can use SetVariable / GetVariable on that unit to save a variable for it.

Also, if you want them to be on solid ground, perform a check against this:

Hmm, I've tried the following;

act = this addAction["Change for land combat","Scripts\DiverGearChange.sqf",this,1,false,false," surfaceiswater [getpos this select 0, getpost this select 1]"];

But it works whether I'm in water or not. What am I doing wrong?

Also, using SetVariable, if I've got the unit named in my .sqf, i.e. _diver = _this select 0, can I do the following?

_diver setVariable ["ChangedToLand", true, true];

Just not sure if I can pass it back like this.

You do realize that your placing the condition in the wrong part of the addaction?

act = this addAction["Change for land combat","Scripts\DiverGearChange.sqf",this,1,false ,false,"","!surfaceiswater [getpos player select 0, getpos player select 1]"];
