Random Python module and creating chances

Question

I have a text adventure game with battle system in place already. It is of course turn based, both player and enemy deal damage points (in float). I use random.uniform() function to generate attack points for every round. Zero stands for missing an enemy or player. However since I use floats that chance is pretty slim. I want to create a condition where there would be let's say a chance 1 in 5 that attack points equal 0.00. This condition must be run on every round.

How would I go about it? Is there a module I could use?

note: I think I could use random module (random.randint(0,5)) but I was wondering if there is some other way. Thanks!

Should your attack points be floating point values or integers? — Martijn Pieters

Both hitpoints and attack points are floats. Maybe I'm just complicating things... I've tried creating conditions with random.randint(0,4) and it works pretty good. But I'm still interested in other solutions. — user3056783

I think you should use random.uniform() reserving 20% of values for 0.00 attack points.

hit = random.uniform(0, 10)
if hit <= 2:
    damage = 0.00
else:
    damage = (hit - 2) / 8

This is just a stupid example but might help. Or even more simple:

hit = random.uniform(0, 10)
if hit >= 8:
    damage = 0.00
else:
    damage = hit / 8

Aaah, I see. Simple mathemathics - should have done this in the first place. Thanks!

I'd suggest rolling two random numbers: One for the chance to hit and another for the actual damage dealt. You could also combine them with player attributes. Example:

if random.uniform(0, 100) < player.chance_to_hit:
    damage = random.uniform(weapon.min_damage, weapon.max_damage)

Yeah I ended up with something like this actually.

You can multiply a chance going from 0 to 1 (float) by a maximum hit damage (int):

try:
    chance = 1.0 / random.randint(0, 5)
except ZeroDivisionError:
    chance = 0.0

damage = chance * MAXIMUM_DAMAGE

Just a guess.

a chance 1 in 5 that attack points equal 0.00.

if random.randint(1, 5)==1:
    attack_points=0.00

|

or if you want to see big true-like numbers:

if random.randint(0, 100)<=20:
    attack_points=0.00
