CODED is not supported #209
Description
key is a char, and CODED is a int, I don't know how to compare those two things
fillVal <- 126
draw <- function() {
fill(fillVal)
rect(25, 25, 50, 50)
}
keyPressed <- function() {
print(key)
print(CODED)
if (key == CODED) {
if (keyCode == UP) {
fillVal = 255
} else if (keyCode == DOWN) {
fillVal = 0
}
} else {
fillVal = 126
}
}

Java automagically converts the char to an int for comparison -- for example, this works:
If this isn't working in R, perhaps due to precedence (?), then perhaps try:
Option 1: change CODED in the list of constants to a char type
Option 2: convert before check:

Thinking about this further, I think that option 1 -- changing CODED to a char in Processing.R -- is the way we should go. The only way that CODED is used in the Processing API is to compare it to key, so this preserves the Processing style of writing
which is what we want. The char(CODED) value in Java should be equal to in renjin something like:
