Savage Vessels

Impressive rogue-like 2D space shooter with pixel-art, physics and hard survival.

Interview with developer KPas

Could you please give a short description of Savage Vessels for those who have never heard of it?

Within fields of asteroids and fragmented freighters you scavenge and
combat against robot vessels. At the same time you have to keep away
from the surrounding void. With your carrier you got into this
threatening area. In order to escape you have to determine your location
repeatedly: leave the carrier, visit some navpoints, land again and move
on. But the robots won’t let you. So you have to arm against them by
gathering and crafting.

The visuals are based on top down pixel-art and a dynamic field of view.
Modern physics provide inertia and collision. Sound fx creates an eerie
atmosphere. It’s a spiritual successor to Teleglitch.

Why did you decide to choose Pascal as a programing language and SDL/SDL2 as a library for this project?

Pascal is my mother tongue. It’s capable of everything I need and I’m
feeling comfortable with it.

SDL is versatile, platform-agnostic and plain.

What do you think is the most interesting Pascal/SDL/SDL2 project out there (besides of your own, of course :-D)?

My nomination for now: DoomRL (https://drl.chaosforge.org/)

Are there any further steps for Savage Vessels and/or are any new projects planned? What will they be?

Savage Vessels is in development and I want to release it on Steam end
of year 2019 or so. You can wishlist it on Steam by the way.

The GoldSrc BSP Loader

Last updated on August 15th, 2018

This project is a program to load GoldSrc BSP files. The GoldSrc BSP file format has been derived from the id’s Quake 2 file format by Valve Software for their Half-Life game series.

It has been realized with

  • Lazarus, Free Pascal
  • SDL2, OpenGL.

 

The BSP Loader powered by Lazarus.
Loading a WAD file and displaying a selected texture from it.
Textured rendering of a scene (estate). The blue colorkey is not interpreted to be transparent yet.
Scene: Oilrig.
Scene: Assault.

02/08/2018, v0.1 alpha

  • Capabilities
    • Load BSP files and show contents of data lumps (exception: VIS Lump)
    • Load WAD files and render contained textures
    • Load BSP file and all WAD files which are necessary to render the fully textured scene
    • Navigate by simple camera through scene
  • To-Do’s
    • lightmapping from lightmap data
    • VIS Lump: treat it at all
    • collision detection
    • face culling
    • have spaces between textures in atlas texture to prevent bleeding-effect (esp. in tiled textures recognizable)
    • make blue colorkey transparent
    • sky cube
    • release the source code (if beta stadium reached)

Important Sources

BSP and WAD File Formats

I cannot state how important these documents were in understanding the structure of the BSP and WAD file formats. Without them, this project wouldn’t have been possible.

Matrix and Vector Functions

I used the SupraEngine.Math Unit by Benjamin ‘BeRo’ Rosseaux (benjamin@rosseaux.com) for this.

Interview with Kornel Kisielewicz

Why did you decide to choose Pascal as a programming language and SDL as a library for your projects?

Kornel Kisielewicz: Pascal was my first language, and in those days C++ was quite messy. I liked the clean syntax of Pascal and it’s default strong type system. SDL was a no brainer, we wanted a platform independent layer for OpenGL context creation and Input handling, and SDL was the only reasonable choice in that regard at the time.

What do you think is the most interesting Pascal/SDL/SDL2 project out there (besides your own, of course :-D)?

Kornel Kisielewicz: I have been out of touch with the Pascal scene for a long time now.

Are there any new projects planned?

Kornel Kisielewicz: We’re currently working on Jupiter Hell, a spiritual successor to DoomRL, but it’s in full 3d, and written in C++.

Interview with Aleksey from Second Variety Games

Could you please give a short description of Monsterland for those who have never heard of it?

Aleksey: Monsterland is a 2D realtime shooter portrayed entirely through ASCII characters. This includes blood, lighting, particles, etc. Its only gameplay mode is a 3-hour story campaign, which has voiceovers, triggers and scripted sequences. The gameplay of Monsterland was heavily influenced by original Doom games (1 and 2).

Why did you decide to choose Pascal as a programming language and SDL as a library for your projects?

Aleksey: Pascal is an underrated, well-rounded programming language. It has good diagnostics and strict syntax, which removes ambiguity from error messages. It also helps that I was first introduced to it in 1992.

SDL was chosen because I’ve also been writing an engine tied to DirectX, and given where Windows is heading, it was a mistake I didn’t want to repeat. SDL 1.2 didn’t have accelerated 2D though, so I had to do it via OpenGL manually.

What do you think is the most interesting Pascal/SDL/SDL2 project out there (besides your own, of course :-D)?

Aleksey: If Dwarf Fortress still used Pascal, I’d name that. Otherwise, DoomRL I guess.

Are there any further steps planned for the Monsterland series? What will they be?

Aleksey: Aw, you flatter, but Monsterland will not be continued.

Are there any new projects planned?

Aleksey: I’m starting to work on a new type of IF (interactive fiction) game. I clearly have an obsession with text visuals.

There’s also the ambitious isometric RPG I’ve been writing in C for years, the “magnum opus”, but it’s too ambitious at the moment, even though a lot of work has been done. I wish I wrote it in Pascal instead – it would’ve been easier to debug.

Interview with Klaus Vor der Landwehr from Turtle-Games

Could you please give a short description of No One’s Space for those who have never heard of it?

Klaus Vor der Landwehr: No One’s Space (NOS) is a single-player Retro 2D-Science-Fiction-Shooter with modern physics. It was created as a cross-breed of the classic games Wing Commander I and Star Control II. In NOS, the player experiences a cosmic conflict between four powerful races, taking the role of different heroes. In 54 challenging missions, reaching from manageable duels to large combats, the player controls a variety of vessels and has to go all out to improve his skills to master them all.

Why did you decide to choose Pascal as a programming language and SDL/SDL2 as a library for this project?

Klaus Vor der Landwehr: It wasn’t really a choice. I’m used to Pascal since my school days. I’m a self-taught. I like it.

What do you think is the most interesting Pascal/SDL/SDL2 project out there (besides your own, of course :-D)?

Klaus Vor der Landwehr: Hm, as far as it concerns the programming language, games are rarely tagged. But I’ve seen some impressive stuff right here: Projekt “W” – Phase 2 http://www.saschawillems.de/?page_id=829 (Although I can only assume that it uses SDL).

Are there any further steps for No One’s Space and/or are any new projects planned? What will they be?

Klaus Vor der Landwehr: If the game gets Greenlit, we want to release it on Steam this year (early access) and work further on it.

Interview with suve

Could you please give a short description of Colorful for those who have never heard of it?

suve: Colorful is a simple game where the player moves freely around a 2D world, fighting multiple enemies and trying to retrieve colourful artefacts. Originally created in 48h for Ludum Dare, the game is heavily inspired by Hero Core, featuring simplistic graphics and sounds, and a no-game-over approach balancing the overall difficulty level.

Why did you decide to choose Pascal as a programming language and SDL/SDL2 as a library for your projects?

suve: I chose Pascal mostly as it’s the language I’m most proficient and comfortable with. As for SDL, after working with a few different libraries in the past, I’ve found SDL easy to use, but nonetheless really versatile and fitting my needs. The library itself doesn’t really enforce anything on you, so you don’t have to change your habits (much), and the seemingly simplistic API is greatly extended by the supplementary SDL_XYZ libraries.

What do you think is the most interesting Pascal/SDL/SDL2 project out there (besides of your own, of course :-D)?

suve: Supraleiter seems the most awesome of them all, I think. Shame that quite probably I won’t be able to play sit, seeing as I only have an integrated GPU.

Are there any further steps for your projects or any new projects planned? What will they be?

suve: I have two projects underway right now, but one is too early in development and I don’t want to disclose it for fear of not delivering… and the other, for a change, is written in C instead of Pascal. 🙂

 

Alexland

Short description

Alexland is a 2d shooter in a classical style.

Showcase and Basic Data

Developer granted permission to use these screenshots.

  • Project name: Alexland
  • Author: suve & ZbiXs
  • Latest version: 1.3
  • First release date: 2010-01-31
  • Compiler: Free Pascal 2.4.0 (for the 1.3 release)
  • SDL Version: 1.2
  • Further libraries: BASS for audio handling, SDL_image, SDL_ttf, SDL_net
  • License: Back then we didn’t really think about licensing, and seeing how the game contains assets ripped from plenty of places without even keeping track of source… I say it’d be hard for us to claim copyright to anything apart from code and some original graphics (+edits) we created.
  • Open source: Nope. Maybe if there’s a remake one day.

Interview with suve

Could you please give a short description of Alexland for those who have never heard of it?

suve: Born of RPG Maker nostalgia and the hatred for its default graphics set, Alexland is a 2D shooter where the player controls a lone hero in a fight against never-ending hordes of monsters. Featuring 12 weapons to kick ass with, 11 bonuses to enhance the gameplay, 10 monster types to kill, and 60 achievements to unlock, Alexland can provide long hours of mindless, merciless fun. Available in English, Polish, French, German and Russian.
