Return value based on multiple bool conditions

Question

I have following case:

enum values{
go = 1,
stand = 2,
jump = 3,
run = 4,
go_stand=5,
go_jump=6,
go_run=7,
go_stand_jump=8,
… and so on 
Go_stand_jum_prun=17}

int select value(bool go, bool stand, bool jump, bool run)
{
}

Based on combination of bool values passed to the method I need to return appropriate value, meaning if go=true and the rest false 1 will returned if all parameters passed in will be true 17 will be returns, the same applies for all combinations in between. The Only idea I have it’s a lot of if and else if statements to evaluate possible combinations, which is sort of ugly. The question is there more elegant solution.

Thank you all!!!

Answer 1

To achieve this you have to modify your enum

enum values {
    none = 0,
    go =  ( 1 << 0 ), // 1
    stand = ( 1 << 1 ), // 2
    jump =  ( 1 << 2 ), // 4,
    run = ( 1 << 3 ), // 8
    go_jump = go | jump
}

Then in your method:

values GetValues(bool go, bool stand, bool jump, bool run)
{
    values result = values.none;
    if( go )
        result |= values.go;

    if( stand )
        result |= values.stand;

    // and so on...

    return result;
}
