# ICE

# Introduction

ICE is a vertical shoot-em-up in tradition of Raptor and Tyrian with vector style graphics written in the D programming language.

ICE is still in very early development and might see large changes.

# Gameplay

You move your ship around the screen, shooting attacking enemies. A basic weapon allows you to shoot forward while, over the course of the campaign, you get more weapons that can be used only once in a while, taking time to recharge (currently, these are always enabled; the gradual ship improvements are not yet implemented).

Each weapon is designed to require a bit of skill and timing as opposed to just being a bigger, more powerful gun.

## Controls

`W`, `Up` | Move up
`A`, `Left` | Move left
`S`, `Down` | Move down
`D`, `Right` | Move right
`Space`, `NumPad 5` | Fire weapon 1.
`J`, `NumPad 4` | Fire weapon 2.
`K`, `NumPad 2` | Fire weapon 3.
`Scroll Lock` | Take screenshot (in `~/.ice/main/screenshots/` if installed, or `user_data/main/screenshots/` in the game directory)
`Escape` | Exit the game while playing.

## Directory structure

Directory | Description
--- | ---
`./` | This README file, utility scripts, source code outside of any packages.
`./data` | Main game data directory, contains data that is never modified.
`./user_data` | User game data directory, contains modifiable data such as screenshots, etc.
`./dependencies` | Source code of libraries ICE depends on.
`./doc` | Documentation.
`./docsrc` | Documentation source code.
`./xxx` | Other directories: ICE source code.

## Dependencies

ICE is written in D, so for compilation it requires a D compiler such as DMD. Currently, only DMD is supported; GDC will be supported once it becomes a part of GCC. Due to linker problems, only DMD 2.058 works on Windows; this should change in future.

ICE depends on Derelict, D:GameVFS and D:YAML, which are included for convenience. SDL 1.2, SDL-Mixer, FreeType and OpenGL are required through Derelict.

## Installing
