[TUTORIAL] How to use Public Variables

[hambeast]

just for shits and giggles, can you declare a clientside PVEH just to spit out some text?

// Clientside PVEH (init this in your mission.pbo)
if (!isDedicated) then {
	// expects []
	"PVEH_PlaySoundClient" addPublicVariableEventHandler {
		systemChat "We got our PVEH";
	};
};

try placing that in your init.sqf along with your server side one.  maybe declare this one first.

I'm shittin', and I'm gigglin'!!  :wub:

 

The PVEH message shows up on my screen as well as the other player who is withing 30m, outside that, the message doesn't show. :D

 

How should I execute the sound? Wouldit just be player playsound "soudname"; :blink: 

[hambeast]

that... is beyond my expertise.  I'm just a simple PVEH coder lol.

 

You could try the playsound command but... I've never messed with it.

Just saw this... IDK if this will be helpful for you but it seems to incorporate the distance in the parameters: https://community.bistudio.com/wiki/playSound3D

 

edit: might not even need a PVEH

I think I got it.... I noticed 2 lightning bolts, I fixed that alread ;)

oh man that is awesome!  Glad to see you got it working

[computermancer]

Yeah, thanks for your help in understanding PVEH, making the server do stuff for me was a big weakness of mine in my scripting arsenal.  :ph34r:

Late to the party as usual but just a couple of suggestions on the code.

 

In the _playersToSend loop, count is faster than forEach if you don't need to use the _forEachIndex special variable in the loop code.

 

nearentities is also faster than nearestObjects.

 

if (isPlayer _x) then {}; will detect if the player is a human player.

 

Hope this helps.

Doesn't count only give a number, where as foreach allows code to be run on each?

Nope.

 

Both iterate through an array and use _x as the current array element inside the loop.

 

forEach allows a second special variable called _forEachIndex which contains the index of the current array element in the loop.  Count does not have this special vairiable but runs faster.  If you do not use this second special variable then they are both interchangable.

[computermancer]

So count does the same thing as forEach, minus the second part (the index)?

 

And this would work for what I am doing which is just checking if they are a player, and then running some code?

 

BTW: Thanks for the advice, I am sure I have A TON of wasteful code!  :rolleyes:
