WATER SIMULATION PROBLEM
Nov 29th, 2006, 2:49am  
Hi,
I'm new to processing and I have been looking at other peoples code and going through the tutorials to figure out how to do stuff.

can someone tell me why the source code to this simultaion returns an error:  
http://bodytag.org/nav.php?u=tp02/
I figured BImage had to be changed to PImage but the next problem was:
float constrain(float val, float minv, float maxv) {  
which returns the error:
Semantic Error: The method "float constrain(float val, float minv, float maxv);" cannot replace the accessible final method "float constrain(float $1, float $2, float $3);" declared in type "processing.core.PApplet".

What does this mean?

If you are using the Beta 121, you should comment this out :

Quote:
/* float constrain(float val, float minv, float maxv) {  
 return (val > maxv) ? maxv : ((val < minv) ? minv : val);  
}  */

This code is also ratio aspect locked (1:1)

If you want to change it you must replace in the source, this line :

Quote:
y = (int)i/HEIGHT;

by this one :

Quote:
y = (int)i/WIDTH;
