Question

I am making a basic little game in Java and I want to have it so that I can use Hashmaps for binding keys..

e.g.- it would be like HashMap
and then I would do:
hashmap.add(Keys.up, VK_UP);

but this is where I get to my problem, How do i access the hashmap and choose which keys are pressed when the KeyListener returns a pressed key?

Sorry if this question seems baffling but I’m really confused too..

Answer 1

You insert key and value to the hashmap using map.put(key,value) and retrieves a value based on a key using map.get(key)

You need to make sure that the class of the keys overrides both hashCode() and equals() [For library classes – it already is]
