Space Engineers - development update 1/27/2014

Summary of multi-player update and what are we working on right now.

The multi-player release was the biggest event since the launch of Space Engineers. It was the most successful and yet the roughest update we had. Most successful - because it tripled the sales of Space Engineers and increased player numbers as well - http://steamcharts.com/app/244850#3m. Roughest - because there were bugs and connections issues (the worst should be fixed in the following update). The good thing is that we did this update only within the community and we didn't announce it publicly. We will announce it but only when the multi-player is stable and more feature-finished.

The interesting lesson from multi-player release is that it was the first update that had visible impact on sales. All previous updates haven’t doubled nor tripled the sales. Multi-player did it. Not all features are born equal and this applies especially to multi-player. The question is: which future change or feature will have a comparable effect. Any ideas?

The next couple of weeks will mostly be about consolidating and polishing what’s already in the game (work in progress or disabled). Our weekly updates may be less frequent and not on Thursdays.

Our programmers are working on finishing the “realistic mode” (this is what some of you call “survival”) – real inventory size, death, re-spawn and manual building.

The manual building is the exact opposite of the creative mode building which is present in the game. In manual building you use a welder to construct blocks from components and grinder for disassembling.

We are working on an algorithm that will allow proper deformation of non-armor blocks. Now if you have noticed, only armor gets deformed and other types of blocks just disappear. This will change soon.

Our artists are finishing the textures for the heavy armor - it has a camouflage pattern on it and is heavier, stronger and can sustain higher damage (collisions, impacts and missile explosions). Heavy armor comes in two sizes – large and small.

They are also finishing the 3D models for multiple phases of block construction (25%, 50%, 75%, 100%) – see the below screenshot.

We have some new guys in the team – two programmers, two artists on internship (Artem and Adam) and a sound designer who already worked with us on Miner Wars 2081, so we are setting up the audio development procedure and already experimenting with sounds.

Our testers are focusing on multi-player testing – they do this on the public Steam branch of the game (this is the branch that’s available to everyone).

Space Engineers - sound design

We are planning to start adding sound effects in Space Engineers so I thought that this is a good time to share with you our preliminary sound design.

This document doesn’t represent the final work and there are things that may change in the future.

World/server in Space Engineers can be configured in one of two possible modes (it’s configured in world settings – therefore in multi-player all clients have the same settings):

• Realistic (no sound in space)
• Arcade (player can hear sounds even if he shouldn’t really hear them)

Implementation rules:

• Realistic mode: player can hear only sounds that are generated somewhere on his or in his body or cockpit/ship
• First-person mode and third-person mode are equal. “Audio listener” is always positioned in the controlled object (astronaut, space ship cockpit). In other words, when the player is in third person mode, “audio listener” is in the head of the astronaut (not where the third-person-camera is located)
• The game should distinguish between sounds generated by the player and by sounds generated by other players. E.g. in realistic mode, the player can hear his own steps, but he can’t hear other players walking. In arcade mode, he can hear them walking, but it may be a different sound (wave file). For these reasons, I am using “player” and “other objects” terminology in the list of sounds.
• These rules must be encapsulated in some audio class, so the code that just wants to play some sound doesn’t need to know about these rules.
• These rules must work in single-player, multi-player, when switching between first and third person, when entering and leaving a cockpit (small or large), when dying and re-spawning, when switching between character through dev keys, etc.
• Material type: rock, metal and human. When two objects collide, we get their material types and play the right sound for this pair of objects (e.g. rock vs metal, metal vs metal, metal vs human, etc.). Voxel asteroids and ore-items are always rock. Small and large ship blocks and other items (components, weapon, etc) are metal. Player character is human.
• I have not decided yet whether sounds in “realistic” and “arcade” modes should be the same or different. E.g. the player shooting a hand weapon in realistic mode will hear a muffled shot whereas in arcade mode he can hear a real shot sound. We can decide and change this later.
• HUD/GUI sounds - these sounds are played only for the player who activates them (e.g. if some other player turns on/off his lights, I won’t hear it).
• Game sounds - We have 2D and 3D sounds. 2D sounds are played if the sound is generated by the player/listener and there’s no distance-volume-curve-attenuation. 3D sounds are played for sounds not generated by the player/listener (other players or objects). 2D sounds are stereo WAV files; 3D sounds are mono WAV files.
