# Basic game physics – fluid movement

An important aspect of almost any game is that things move right. The movement of objects needs to feel natural or intuitive, so that the players can interact with them effortlessly. We can use the manipulation of velocities and accelerations in order to achieve this.

# Basic game physics – from Newton to code

While we my not often think about it, movement of objects is one of the key aspects of most video games. In any game that has any sort of characters, enemies or items interacting in a fictional – or real – world, these agents and objects have to move in order for anything to happen.

In most cases, we want these movements to appear natural, or at least believable and consistent. This allows the player to better put themselves in the feet of the protagonist, or avatar, as they can control their movements in an intuitive way – not having to think about each key press individually, but merely willing to move in a certain direction and letting muscle memory take over from there.

# Brainstorming civilian AI

One of the projects I am currently working on is a game called Centipede in which the player controls a giant centipede in a city with the goal to cause as much havoc as possible.

Next to damaging and destroying buildings, vehicles, and other static objects, there are of course a large number of humans to serve as snacks, or – if armed – nuisances.

To make the game fun and engaging, it is important that these simulated humans react at least somewhat realistically to the chaos developing around them.

Ideally, their behaviour would also be reasonably complex and not entirely predictable, to make interacting with them more interesting.

# LINQ Batch extensions: A correction

In a post last year I explored how we can use LINQ to batch or page items from a collection in such away as to return a sequence of sub-sequence, each having equal length (except for possibly the last one). In that post I made a significant mistake that I would like to correct here.
