[AMXX] Run time error 11: divide
[AMXX] [0] amx_fire.sma::fire_flamethrower (line 179)

179 line is:

PHP Code:

velocityvec[0]=velocityvec[0]*speed/length 


Any help pls! What exactly means divide error?

It is simple math. You have multiplication and dividing in one expression. Just put some brackets () on the multiplication or in the dividing. Depends of what you want but in this case I think you should put the multiplication expression in the brackets.

[Gasa]

Hm can u give me example?

[Flick3rR]

PHP Code:

velocityvec[0]= (velocityvec[0]*speed) / length 


or

PHP Code:

velocityvec[0]= velocityvec[0] * (speed/length) 


[Gasa]

Thx for help, this means if u dont follow math rules in dividing u will get error!

[Black Rose]

I think it's because you're dividing by 0.

This should not be necessary. Order of operations is handled correctly by the compiler (afaik). In light of that, there is no difference between multiplying first or dividing first.

However, one major flaw here is that the variables are not floating point variables which will result in integer division. This is occasionally beneficial but not in this case. The sqrt() outputs a floating point value but "length" is not floating point.

The error is probably occurring from a division by zero.

You are right same error even with () .But if i check is lenght == 0 ,flame not working!

[HamletEagle]

Then, you should not divide by 0.

PHP Code:

velocityvec[0]=velocityvec[0]*speed/length
velocityvec[1]=velocityvec[1]*speed/length
velocityvec[2]=velocityvec[2]*speed/length 


->

PHP Code:

if(length != 0) {
    velocityvec[0]=velocityvec[0]*speed/length
    velocityvec[1]=velocityvec[1]*speed/length
    velocityvec[2]=velocityvec[2]*speed/length
} else {
    velocityvec[0]=velocityvec[0]*speed
    velocityvec[1]=velocityvec[1]*speed
    velocityvec[2]=velocityvec[2]*speed
}
