I was playing around with some codes but couldnt see to figure it out. Does someone here know how to make the Energy stat on the profile recharge a little and in 10 min it would be fully recharged?

[phpdoctor]

Do you have any code already?
Could you explain alittle more, whats the energy?

[Ishmell]

No I dont have a Energy recharge code yet. Energy is a stat in my browser based game which is a field in the profile section of the database. The user has 100 energy at the moment and lets say the user does a crime which subtracts energy to do the crime. So the energy goes from 100 to 50. Now I want a script that would activate and recharge it back up to 100 again over time.

Oh, that Energy Code, the one that doesn't exist yet and that you didn't bother to explain or provide an example of. Right. Gotcha.

Based on what little you did say, what you probably want is a cron job that runs periodically to reset the "Energy Code value.

Without providing a more coherent explanation (and maybe some code) no one here can give you much more than a generalized answer (i.e. "use a cron job").

yeah I think thats what its called to. Well I really dont have any code for the Energy but the subtract code that takes energy away.

PHP Code:

$_SESSION['Energy'] -= $amount; 

I can use that code for like after crimes and stuff but I need the regerate energy code which I did hear somewhere on msn that it was called "cron job"

Do you know any Javascript?
Because that is what you will need to setup a timer.

Really? I no none whatsoever but I also herd a while back you could do these things in php as well. I also herd there were do ways of doing this. One was where the energy would rechrage slowly till its full and the other is its recharges completely after a certain number of minutes. Doesnt really matter whichever someone could help me out with. Either one would be perfect.

This can be done by time stamping a particular event (when the energy for this character last changed) and keeping that time stamp / energy level after the change in a database.

When the user views his character, you take (current time) - (timestamp time) and base the user's energy level off of that (you can update the database while you are at it).

This method doesn't rely on cron and is only updated when the user is visiting the website (the only time the user's energy really needs to be updated). This method requires you to have a new table in your database that holds energy and timestamp for each user.

To recap (in order):
1. User's energy level changes (perhaps the user was hit or something).
2. You place the user's new energy level into a database with a timestamp of the current time.
3. Whenever your game needs to display this user's particular energy level (I am assuming this ONLY happens when the specific user is interacting with the system), you game fetches the time stamp and new energy level from the database.
4. Determine the difference between the current time and the time stamp and multiply it by some value to get the user's energy level. NE = ((current time) - (timestamp))*rate_of_energy_recharge
5. Take (NE) from above and update user's energy in the database (i.e. probably where your user table or attribute table is I am guessing) ~ NOT the timestamp time.
6. When enough time has elapsed or a the user's energy level has changed again (i.e. the user has been hit again), update the user's energy / timestamp in the energy timestamp table.

That would be the basic and most obvious setup here. A good example of #4 equation:

PHP Code:

$timestamp = ... fetched from timestamp table ...

$old_energy = ... fetched from timestamp table ...

$current = time();

$rate = 5; // 5 energy points / second 

$user_energy = 3000; // the user's energy when fully restored, pulled from your user or attribute table



$new_energy = ($current - $timestamp) * $rate;



// if we are finished regenerating

if ($new_energy >= $user_energy)

{

    // store $new_energy into user's attribute table

    // remove energy timestamp from timestamp table database

} 

This method will work best if your script has ONE function to update a user's energy level. If your script update's the user's energy level from multiple locations, then you will want to include the code you come up with that calculates the user's energy from the timestamp db into the header / global portion of your script (so it is loaded every time to ensure that things such as shops work correctly).

Okay im pretty sure I get this code. Where it says ... fetched from timestamp table ... is it actually doing something or do I like put something there?

[Patiek]

I just gave you pseudo code... you need to fill in the gaps. You need to come up with the code for "fetched from timestamp table" (some mysql select, etc).

If you wanted to actual code you should have submitted a script request.
