hello! i am making this game in Processing and using a Teensy hooked up to some buttons to play the game. you know the drill haha. well… i am getting this amazingly frustrating error almost everytime i run the program, and this error wasnt happening a few months ago either…
It must have to do with this serial port maybe overflowing?? idk. ive tried stepping through the code, but it sometimes doesnt happen until the code has cycled like hundreds of times.
here is the error on Processing 3.5.4
ArrayIndexOutOfBoundsException: -1
java.lang.ArrayIndexOutOfBoundsException: -1
at processing.serial.Serial.serialEvent(Unknown Source)
at jssc.SerialPort$EventThread.run(SerialPort.java:1112)
and here is it on Processing 4.0
ArrayIndexOutOfBoundsException: Index -1 out of bounds for length 32768
java.lang.ArrayIndexOutOfBoundsException: Index -1 out of bounds for length 32768
