Boolean
If you want your character to stop before a wall a method (which return type is boolean) would be easyer.
In the method you can check whether there is a wall in front of your caracter.
But to help you writing this method we need some more information about how your scenario works.
For example is the cell size 1px or more (you can look it up in the world constructor), or in which directions does your caracter move?
My character moves 1 cell per "click", i move him with w-a-s-d! 1 cell left/right is y+/-1 and 1 cell up/down is x+/-1!
But I want my character to check if there is wall ... just check!
Thank You!
to just check you need to use the method getOneObjectAtOffset.
I think the use of a parameter would be good in this case:
this method will return true if there is no wall in the direction you check
public boolean nothingInTheWay(char direction) {
switch (direction) {
case 'w'://up;
Actor wall = getOneObjectAtOffset(0, -1, Wall.class);
return wall == null;
case 'a'://left;
Actor wall = getOneObjectAtOffset(-1, 0, Wall.class);
return wall == null;
case 's'://down;
Actor wall = getOneObjectAtOffset(0, 1, Wall.class);
return wall == null;
case 'd'://right;
Actor wall = getOneObjectAtOffset(1, 0, Wall.class);
return wall == null;
default:
return false;
}
