mixing active and static modes

in Programming Questions • 8 months ago

I'm trying to make a simple function to transition from one color to another, but I get the error "It looks like you're mixing "active" and "static" modes. Here is the code:

int[] fromRGB = { 100, 0, 255 };
int[] toRGB = { 50, 0, 0 };
void makeTransition(int[] fromRGB, int toRGB, int time){
for(int i = 0; i < 3; i++){ // loop through R,G,B
if(fromRGB[i] != toRGB[i]){ // make sure they are not already at correct R, G, B
if(fromRGB[i] > toRGB[i]){
fromRGB[i]++;
println(fromRGB[i]);
} else { fromRGB[i]--; }
}
}
delay(time);
}
makeTransition(fromRGB, toRGB, 1000);

any ideas?

Well, definitely you are mixing them!

If you create any functions, like that makeTransition() one,
you can't call it outside a function/method.

Let's put that call inside setup():

void setup() {
makeTransition(fromRGB, toRGB, 1000);
exit();
}

Also, your function creation parameters is supposed to be 2 int[] arrays + 1 normal int;
but you only declare 1 int[] + int!

Here's the fix:
void makeTransition( int[] fromRGB, int[] toRGB, int time ) {

void setup(){size(220,220);}
void draw(){background(lerpColor(color(100,0,255),color(50,0,0),(millis()%10000)/10000.0));}

ah, thanks for replies.

and thanks tfguy too, I did know about lerpColor--however I wanted to learn how to write the function myself just because I am so new to Java :) plus I am sending the RGB values to arduino via serial, so I need them to stay arrays. Would there be a way to return an array, or extract the values?

I will try both ways.
