Starting to do some experiments with blending modes in jit.gl.pix with codebox.

And i want to pick the blending mode with param selection (int 1,2,3)

if selection == 2 then out1 = multiplication

if selection == 3 then out1 = subtractive

I cannot get selector to work in codebox (the documentation isn't clear to me with how to do this in codebox at all, could we also get the documentation just to include a clearer way of using all the operators with codebox with examples ? If i'm being an idiot and missing the obvious then please point it out !)

Maybe I'm approaching this the wrong way and need to do it with functions. Can't get that to work either..

If anyone could help with a basic example that would be great. An example showing both methods would be legendary ;-)

Starting to do some experiments with blending modes in jit.gl.pix with codebox.
Lets say I have 3 blending modes
additive (in1+in2)
multiplication(in1*in2)
Subtractive(in1-in2)

And i want to pick the blending mode with param selection (int 1,2,3)
if selection == 1 then out1 = additive
if selection == 2 then out1 = multiplication
if selection == 3 then out1 = subtractive

Crystal clear for normal use with nodes but a clear codebox example would be welcome.

From the manual in reference
Constructors

{ arguments={choices}, inlets={...} }
{ arguments={}, inlets={...} }

Crystal clear for normal use with nodes  but a clear codebox example would be welcome.


Well of course I just nailed it after posting it on the forums.

final = selector(click,multiply,additive,subtractive);

Param click(1);
multiply = in1 *in2;
additive = in1+in2;
subtractive = in1 - in2;
final = selector(click,multiply,additive,subtractive);

That's a great way to do if if you need named variables. Otherwise you can just use:

out1 = (click==1) ? in1*in2 : (click==2) ? in1-in2 : (click==3) ? in1+in2 : in1;

effect=in1;
if(click==1) { effect=in1*in2; }
else if(click==2) { effect= in1-in2; }
else if(click==3) { effect=in1+in2; }
else  { effect=in1; }
out1 = effect;


That's a great way to do if if you need named variables.  Otherwise you can just use:

So if I'm understanding it correctly with selector...

(condition to check) ? run code : (what do the double points/colon do ??? )

That is a great explanation Metamax !
 Thanks !

condition to check ? do this if true : do this if false

condition to check ?  do this if true : do this if false


You can also use regular arithmetic with the conditionals:

out1 = (click==1)*(in1*in2) + (click==2)*(in1-in2) + (click==3)*(in1+in2) + (click>3&&click

You can also use regular arithmetic with the conditionals:out1 = (click==1)*(in1*in2) + (click==2)*(in1-in2) + (click==3)*(in1+in2) + (click>3&&click

That door with programming with code and logic just opened a little bit more !

Thank you so much MetaMax !
