Variables exceeding their limit

quantumsheep

Hey all!

I'm wondering if I'm doing something wrong (probably am).

I'm using integer variables to control certain things - e.g. how many power-ups you can use.

I don't want the player to have more than four power ups. So I put in a rule 'If powerups is equal to, or greater, than 4, make the powerups =4"

It seems though that on occasion, and more and more frequently, the variables *do* go above 4 for example.

Is there a rock solid way of getting a variable to stop at a certain number?

Hope that's clear?

Cheers,

Oh, and apologies for all the questions lately! I wouldn't ask if I wasn't honestly stuck!

my idea about a rock solid way :

var_power_up = x;
var_rock_solid = min(4, var_power_up);

does it rock?

I don't get it

CodeMonkey

Take a look at what causes your integer to increment when you gather a powerup. Add the condition in it that says if your power_up_count is < 4, then act as normal.

Funnily enough, I worked that out by myself would you believe! A little thought, and perhaps writing it out to try and explain it to someone else maybe kick starts my brain cell!

Thanks for your input though!
