[SOLVED] minus!!

[grlayouts]

if i have an attack script

 

$mypower = ($mywep[power]  + $stat[strength] - ($earm[power] / 2)); \\player

$epower = ($enemy[strength]  +  $ewep[power] - $myarm[power]); \\enemy

 

if player power = 20 & enemy power = -10 how do i make it so it cant go into negative?

 

 

[ToonMariner]

yo need an if statement in there right after you hav done the calcs on power.  Check if either are <= 0 if they are then stop the contest if not carry on.

[grlayouts]

tried that and couldnt get it working?

[grlayouts]

no tried again still cant get it working.

[Jessica]

You wanna post a little more code and why it's not working.

[grlayouts]

thats it..

 

the above code is the problem.

 

i just need to know if one of them queries = -something how i can default it to '0'

[The Little Guy]

Try this:

<?php
$user_power = -10;

if($user_power > -10){
# do some damage
}else{
# don't do damage
}
?>

[grlayouts]

so

 $mypower = 0 where $mypower <0

should work?

[Jessica]

sure.

[The Little Guy]

are you sure that will work?

I didn't think that would work.

<?php
$mypower = 0;
if($mypower<0){
#can't attack
}else{
#allow attack
}
?>

[grlayouts]

your right it didnt.. i think she just agree's to anything.. lol!

[grlayouts]

$mypower = ($mywep[power] + $stat[strength] - $earm[power]);
if($mypower<0){ ($mypower=0);
$epower = ($enemy[strength] + $ewep[power] - $myarm[power] );
if($epower<0){ ($epower=0);

 

this still aint working, when i run the script i get

Fatal error: Unknown function: attackback() in /home/hobotown/public_html/battle.php on line 566

You're still not posting the relevant code, that's why I agreed. You posted SQL statements, and what you wrote will work in SQL. Your code has nothing about the function (attackback()) that the error is referencing.

 

You said you tried the suggestion Toon posted, yet when I asked you to post it you said you had, but the code doesn't have his suggestion.

 

This code is missing brackets:

 

$mypower = ($mywep[power] + $stat[strength] - $earm[power]);

if($mypower<0){

  $mypower=0;

}

$epower = ($enemy[strength] + $ewep[power] - $myarm[power] );

if($epower<0){

  $epower=0;

}

 

[grlayouts]

because the other code i know works.

[Jessica]

How are you so sure? You can't figure out how to do an if statement, but you're sure the rest of the code works? I'm not saying post all the code, but the ERROR is very specific about the function and the line, and what you posted has nothing to do with it.

 

What you posted was incorrect code however, and if you fix the brackets that may fix it.

[grlayouts]

because i wanted to avoid if statements if possible, my battle script is 800 lines, reffering back to functions ie function attack() { with globals

 

global $stat;

global $enemy;

global $myarm;

global $mywep;

global $earm;

global $ewep;

 

i know it worked.
