This week's book giveaway is in the NodeJS forum. We're giving away four copies of Serverless Applications with Node.js and have Slobodan Stojanovic & Aleksandar Simovic on-line! See this thread for details.
Fisrt of all forgive my ignorance, I'm only 5 weeks in on the language. Im working on a 2d Boolean array that is represented as an imaginary floor, when moving my "rat" across the floor(also the name of the array), I need to be able to leave a trail if it is toggled by the user. almost all of the coding is done but I do not know how to return a Boolean value into a "floor space" as I travel across it can someone just give me a general idea of how to place a boolean value of true onto a 2d array that is already default as false? please do not give me the complete answer, just a gental kick in the right direction. thanx
If I understand what you're looking for, a simple assignment should do the trick. Because you capitalize Boolean, I'm assuming you are using Boolean objects, not primitive data types. You can't modify a Boolean object because the fields are final and there are no setter methods anyway. If you have an array of rows and objects, then you could create a new Boolean with the desired value and assign it to the array element you need to change.
Hope that helps...
