random?

Hello

How do i exclude a number of random?

Some example:

Set value1 to random(5)+1 * This sets value to a number between 1 and 5, right? Now let's say value1 got the random number 3.

Now i wanna do:

Set value2 to random(5)+1 "but exclude value1" * What would in this particular time mean "Pick a number of 1,2,4,5"

I hope you understood what i mean?

Well, what you could do is set up your events so that if it picks 3, it does another random(5)+1 check. So in essence, it will completely ignore it by re-rolling if it rolls up a 3.

I'm getting mad here. It's all not working! Bah!

And, while i'm here, why are some events red?

The red events are fired first.

What Shawn says is the best solution. You can accomplish it by running a fastloop until a valid random number is picked.

* Button1 is clicked
- Set Value1 to Random(5)+1
- Start loop "PickRandomNumberForValue2" 1000 times

* On loop "PickRandomNumberForValue2"
- Set value2 to Random(5)+1

* On loop "PickRandomNumberForValue2"
+ Value2 <> Value1
- Stop loop "PickRandomNumberForValue2"

This last two events tries to set the random value 1000 times. If it picks a value that is different from Value1, it means it has succeded and doesn't do any more tries.

Okay, so what i'm doing is i let the enemy decide in what direction to move (top down view, 4 directions only).

On enemies loop an animation is played that has an 'arm' to all 4 directions. Frame1 = arm to the top, Frame2 = arm down, etc. To see if there is an obstacle.

Now i write in 4 alterable values standing for top, left, right, down either a 1 for no obstacle or a 0 for obstacle.

Szenario:

The enemy is standing, on top is an obstacle, to the left, right and down not.
That would make alterable value
A = 0
B = 1
C = 1
D = 1

How do i make him pick one of the legit variables, without starting another loop or using up to 100 events...?

Anyone an idea or a workaroud?
