Random Treasure chest drops problem.

[PiXLCAT]

This is the last problem to my script project.

I am trying for a treasure chest to drop random drops but here is my problem.

I want them to drop a random Gold Coin (1,2,3) number or a random item such as an apple, carrot, banana, etc.

I have a script right now but it doesn't seem to work well and I am not sure how to proceed anymore to get what I want.

set .@r[0], 671; //Gold Coins
setarray .@a, 0,1,2,3; //Amount(Random)
getitem .@r[0], .@a[rand(getarraysize(.@a))];

set .@r[1], 512; //Apple
getitem .@r[1], 1;

set .@r[2], 513; //Banana
getitem .@r[2], 1;

set .@r[3], 514; //Grape
getitem .@r[3], 1;

set .@r[4], 515; //Carrot
getitem .@r[4], 1;

This script obviously does not work.

Thank you for helping and sharing the knowledge with me.

It's easiest not to split two separate scenarios (random gold coin or constant fruit). Rather, group them into a single array:

// Format: <ID>,<Amount>,{...}
setarray .@i[0],671,1,671,2,671,3,512,1,513,1,514,1,515,1;
set .@j, rand(getarraysize(.@i)/2);
getitem .@i[2*.@j], .@i[2*.@j+1];

I'm still in a learning phase when it comes to arrays and this is very useful information. Thank you so much, your code taught me something valuable today. I will go try it out!

Although I wonder:

rand(getarraysize(.@i)/2)

What is the /2 for?

Since <ID>,<Amount> will always start on an even number, you want to restrict rand() so that you'll always get a predictable result.

I... don't think I understand. ^^;

Sorry, I'm a bit slow at times.
