Need help calculating drop rate rarity

[X-Death]

say you roll a random number between 1-100

if the random number is between 1-95, would this be a 95% chance?

and then if the number rolls between 95-100, this would be a 5% chance?

I'm trying to figure out a good way to do drop rates in triggers.

If you mean random number between 1-100 == number between 1-95, then number between 1-95 will be 95%, same as random number between 1-100 == number between 96-100 would be 5%.

If you mean random number between 1-100 == ExactlyNumber(Example "4"), then it would be 1%.

If the random number between 1-100 == random number between 1-100, then i not too sure if this is also 1% since it is hardly to achieve the exactly same number(Both numbers are random!).

Confused.

What's a good way of calculating, for example, a 5% chance to drop an item from killing a monster?

An example trigger is always the best and simplest way to explain every things

• If (All Conditions are True) then do (Then Actions) else do (Else Actions)
  • If - Conditions
    • -------- check if random number equal to or greater than 96--------
    • (Random integer number between 1 and 100) Greater than or equal to 96
  • Then - Actions
    • -------- Here is actions (5% is achieve)--------
  • Else - Actions

There'er lot of way to achieve % drop rate, just depend on yourself. This's just the one of the method.

Random integer between 1 and 20 equal to 1.

In the case of 95%
random integer between 1 and 20 less than or equal to 19.

Random integer between 1 and 20 equal to 1.

In the case of 95%
random integer between 1 and 20 less than or equal to 19.

Perfect! Thank you.

Thanks, DD_legionTN.

+rep to both of you.

For anything that is very rare (say 0.1% chance or lower) it may be a good idea to have some accumulating buffer that increases chances over time. This is to prevent players being "screwed over by the RNG" which was a major problem in Diablo III before they introduced such a system on legendary items.
