How do I compare two values between each other?

Instead of using the compare two values event:

if 'random(100)

< Less or equal

50'

(that's a 50% chance for the event to trigger)

how can I say

'random(100)

<Less or equal

Between 50 and 70'

To add context, my way of understanding % in construct is by using Compare two values. The setup I just showed involved the construct 2 engine choosing a random number between 0 and 100, and if the number chosen is below or equal to 50, then the event will trigger, thus 50% chance.

But, what if I want to have it trigger if the number falls between two specific numbers? Such as the 'Between 50 and 70' example I gave.

Can you please explain how I can convert my earlier method using this?

Let me add on to this, I didn't explain very well.

I have a set of events that change a sprite's animation frame at the beginning of the layout.

For this, I have set up:

'For Each Sprite

---if 'random(100)

---< Less or equal

---50

------------------------------->Set Animation Frame 0

---if 'random(100)

---> Greater or equal

---51

------------------------------->Set Animation Frame 1

---if 'random(100)

---<Less or equal

---3

------------------------------->Set Animation Frame 2

So, that's a 50% chance for 0, 50% chance for 1 and 3% chance for 2.

Except that equals 103% and makes no sense. So, I need the 1st and 3rd events to be in between two values so the possible outcome of the random(100) number doesn't overlap. I hope that made sense.

Using is between values:

If Value: random(100)

Lower bound: 50

Upper bound: 70

That checks if the randomly generated number is between 50 and 70. So for the first event I guess you need to use this for between 4 and 49.

The condition works like this : Test if a number is between two values (greater or equal to a lower value and less or equal to a higher value).

Okay. Now it's:

For Each Sprite

---- If value random(100) LB: 50 UB: 100 ---> Set frame to 0

---- If value random(100) LB: 2 UB: 50 ---> Set frame to 1

---- If value random(100) LB: 0 UB: 2 ---> Set frame to 2

Except, for some reason despite frame 2 having only a 2% chance, it's the one that appears the most. I know it's completely random and there's a chance that it's landed on 0, 1, or 2 for random(100) each time, but that seems unlikely. Any ideas?

You've got some conflicting logic there, remember it's greater or equal to lower and less than or equal to higher, so 50 and 2 are true for at least 2 of those scenarios. Youll probs want 50 and 100, 4 and 49, 0 and 3.

Alright, I've changed everything to how you said, but frame 2 is still appearing way more often even though it's 0 and 3 now (3%)

Scratch that, entirely my fault. I had a different way of randomizing them before and forgot to delete it. Apologies for wasting your time, thank you for your help!
