Randomly choose between 4 options

[art3mis]

What's the most efficient way in vex to choose between 4 different options? Right now I am simply using rand and a series of if statements to check the resulting value. Is there a better way?

you can use sample_discrete() function to get the index and then get your value from an array of values, it can be uniform or weighted

or you can use ramp parameter with constant interpolation and look up the value using random 0-1 number

i like this way
like you said rand, but with floor function

 

@choose=floor((rand(@ptnum)*4)+1);

Thanks. Is there any way in vex to incorporate method calls directly with your solution, or would I still need to use an if, else once I get my @choose value?

just pick the value from an array based on that index
