Executing a function from a string, adv

08-04-2007, 02:11 AM

Code:

   
set Dir[1] = "East"
set Dir[2] = "West"
set Dir[3] = "North"
set Dir[4] = "South"
if i<3 then
    set x = ExecuteFunc("dir" + dir[i] + "(" + R2S(x) + ")")
 else
    set y = ExecuteFunc("dir" + dir[i] + "(" + R2S(y) + ")")
endif

Code:

function dirNorth takes real y returns real
 set y=y+50 
 return y
endfunction

function dirSouth takes real y returns real
 set y=y-50 
 return y
endfunction

function dirEast takes real x returns real
 set x=x+50 
 return x
endfunction

function dirWest takes real x returns real
 set x=x-50 
 return x
endfunction

How could I execute a function from a string and save the returned value to a variable?

PipeDream	ExecuteFunc() isn't an eval(). It can only call functions of no arguments and no return value. You need to arrange for IO yourself. Typically you do this with global variables. Search the forums for example uses.

ChaosWolfs	x.x Was thinking of using global variables next. Thanks again.
