Radom Variable [SOLVED]

[ShadowMainZERO]

Okay, I'm trying to make a minning/smithing system using common events and I only need to know one thing: How do you set a random variable? You know like you have a/n x% chance to get item y and a/n d% chance to get item w.

The only thing that would make the base stats differ is what kind of pick axe you are using and maybe where you are.

If you go to Set Variable, you'll notice that there are tons and tons of options. One of them is Random.

Oh, well. I should probably have clicked the button first. Although I naver have used variable's before. So would I creat a variable for each item? Seting the random button for the percentage you would you will find said item?

 

[Unka Josh]

I don't think that you would need to. If you want to check if several different items show up, you can just re-use the variable. If you want to make one roll with several possible results, you definitely only need one variable.

Okay, let me explain how this works since I am still confused.

- You have four ores: Copper, Silver, Gold, and Mythril.

- Each item has a certent percentage in which you can find said item. Ex. 70-90% chance to find copper.

How would one go about doing that?

You set a variable to a random number from 1 to 100. Then, you use a conditional branch to see of the variable is within a certain range of values (for a 70% chance to find something, you need the variable to be anywhere from 1 to 70 to get whatever you find.)

Okay, I get that, mostly. The only thing I don't understand is the conditional branch to check the value of the variable. Wouldn't the variable set from,for a 70-80% chance, 70 to 80?

depends what you mean. If you are doing it DnD style, then you generate a random variable and the outcome will be changed depending on what the variable is. E.G., in DnD you roll a die and, if the die if 1-90, you get one thing, and the rest may give you different results depending on the exact number rolled. (Just an example) If you want a straight out 70% chance, then you generate a number from 1 to 100, and any value between 1 and 70 will result in the 70% being true.

Seams simple enough. Although, what if I were to use multiple variables in one event how would I make it so I dont get the same one?

I did the first part okay. *sigh* Now, one last thing then I what about using variables to determin how many of an item you have in stock?

 

[friend]

Just add the items to the inventory.

The player should be able to see them there.

 

[ShadowMainZERO]

I know how to add items. I need to know how to see how many the player has in stock.

Say they had 4 copper ores. How can the game see that and not let them make 5 copper bars?

 

[Unka Josh]

Control Variables can set a variable equal to the number of an item in inventory. You can then display that number by adding \n 

 

[ShadowMainZERO]

Than you. Now that that is over (hopefully), what about my second question?

(Strang, Iposted this message before and it said that it posted it, I even saw it, but it didn't... :huh:

 

[Unka Josh]

Sometimes RMXP.org seems to do that.

Anyway, which second question do you mean? If it's "How can the game see that and not let them make 5 copper bars," the answer is "With Conditional Branches."

 

[ShadowMainZERO]

Weird.Any I have figured out. All I have to do is iorn out some bugd and add some finishing touches and it will be done.
