return boolean type not working?
Mar 21st, 2007, 4:09am  
The following code is supposed to flip a drawing mode switch. It seems to look ok...


public boolean drawMode(boolean drawMode2){
   if(keyPressed && key == 32){
     drawMode2 = !drawMode2;
     return drawMode2;
   }
 }

Semantic Error:
The method "boolean drawMode(boolean drawMode2);" must contain a return statement with an expression compatible with type "boolean".


This is an example from  http://processing.org/reference/return.html

int timestwo(int dVal) {
 dVal = dVal * 2;
 return dVal;
}

What rule am i miss here? Thanks in advance.

you return statement is inside an if-clause. you have to either move it out of there or include another default return after the end of the if-clause (or inside else).
