HMP File – What is .hmp file and how to open it?

HMP File Format

HMP files are binary files that store heightmap data for levels in the Worms game series. Heightmaps are used to define the terrain of a level, and they contain information about the elevation of each point on the map. This information is used to create a 3D representation of the level, which players can then navigate and interact with.

Worms Height Map Editor

HMP files are typically created using the Worms Height Map Editor, which is a standalone program that allows users to create and edit heightmaps. The editor provides a variety of tools for creating different types of terrain, including mountains, hills, valleys, and rivers. Users can also import and export heightmap data in a variety of formats, including BMP, PNG, and TGA.

Opening HMP Files with Worms Armageddon

Worms Armageddon, developed by Team17, is the primary application associated with HMP files. These files are Height Map Files, which contain data describing the terrain geometry of Worms Armageddon maps. To open an HMP file in Worms Armageddon, follow these steps:

1. Launch Worms Armageddon and go to the “Create Game” menu.
2. In the “Map” section, click on the “Load Map” button.
3. In the file browser window that appears, navigate to the HMP file you want to open and select it.
4. Click on the “Open” button to load the HMP file into Worms Armageddon.

Once the HMP file is loaded, you can tweak its settings, such as the number of worms, team names, and other gameplay options. After setting up the game parameters, click on the “Start Game” button to start playing on the map created from the HMP file.

Alternative Methods for Opening HMP Files

In addition to Worms Armageddon, there are a few other ways to open HMP files, although these methods may offer limited functionality compared to opening them within the game itself.

• Text Editor: HMP files are plain text files that can be opened using any text editor. However, this method only allows you to view the raw data and does not provide any interactive editing capabilities.
• Third-Party Map Editors: Specialized tools like MapEdit, Tiled, or Pyglet may support importing and exporting HMP files, enabling you to edit the terrain geometry and other map elements. Keep in mind that the compatibility and feature support vary depending on the specific map editor used.

HMP File Format

The HMP file format is exclusively used in the strategy game Worms Armageddon and its expansion packs. It stores height maps, which are two-dimensional arrays of integers that represent the elevation of a terrain. Height maps are essential for determining the line of sight, projectile trajectories, and other gameplay-related calculations.

The HMP file format has a simple structure. It starts with a header that includes information such as the width, height, and depth of the height map. The data section follows the header, and it contains the actual height values. The height values are stored in row-major order, meaning that the first row of the height map is stored first, followed by the second row, and so on.

Applications of HMP Files

HMP files are only used in Worms Armageddon and its expansion packs. They are essential for generating the game’s terrain, which consists of a series of height maps that are stitched together to create a seamless world. HMP files can also be used to create custom terrain for the game, which allows players to design their own levels.
