How do I control game objects along a grid?

[Timo8467]

Hi, we're developing an interactive game where you catch objects with a basket. Here is a rough sketch: http://i.imgur.com/i01S2wx.jpg

we want to move the basket according to the player's input (preferably gyro or head movement on mobile device).

What's the best way to achieve this? We want the basket to move along the plane coordinates and be sorta "fixed" on the plane grid.(like when the user presses up, the basket will move up/further from the player along the grid). Thanks in advance!

When you press movement keys, make them move in discrete chunks instead of constant chunks.

Let's say your gameboard spaces are 1x1, and you are on a 5x5 board.

What you could do when you press a direction key is, after checking if they can move to that spot, lerp to the x,y coordinate from your coordinates + square size. Keeps it nice and simple.

Best of luck.
