  Today i made some smart roguelike console. For speed improvements i mention some tricks. Listen carefully. 1.do not use ttf fonts, they look cool but are slow to render even on a good machine -> fix t... Continue reading

  
• android GPS and other sensor for LOVE2D.
  May 23, 2025 by Bastian

  I made some major progress while trying to figure out if it is even possible to use external aps on android to make the sensors really work for game or app reasons. And the answer is YES! There it is,... Continue reading
• screen flickering
  May 16, 2025 by Bastian

  I was about to make another small game this time roguelite where the character moves in camera by 8px on screen. But is stays always at the center 64x64 of the window no matter what. So i made the usu... Continue reading

• leeeerpiiiing is haaard
  May 14, 2025 by Bastian

  First timer needs to know that meters/second is something that we will call distance/time thus ds. A dog will travel from A to B distance = 100 px. A dog goes fast as speed = 50. Thus ds = speed/dista... Continue reading
• canvas speed
  April 02, 2025 by Bastian#canvas, #love2d

  Now in LOVE2D when you just starting maybe you need to use canvas for some pixel operations when drawing. But suddenly the speed of drawing is reduced to snail speed and you wonder what happened. Firs... Continue reading
• memory and garbage collecting
  March 26, 2025 by Bastian

  Important thing is not to lock memory when using objects which are connected to other objects and will be released while still the other object exists. Example can be this : i have a scene object. In... Continue reading
• object inheritance
  March 19, 2025 by Bastian

  I decided to try out object inheritance in a way that prevents me from using objects to create more mess than i would need. So in order to work like this i have only single object class used for every... Continue reading
• exporting
  March 08, 2025 by Bastian

  Nice theme. Exporting data in programs for your own code. The bad thing is, most programs do not have an api you could use to export the data produced by that app. It would be great to just look and s... Continue reading
• light and shade

  Long time not written so i begin with the hardest task of them all. How to do in 2D something that looks cool and looks like light that even projects shade from hitting buildings etc. Haha, easy task... Continue reading

  
• day nigh cycle
  February 24, 2025 by Bastian

  For this nice effect i prepared 4 gradient textures for transition between night -> morning -> day -> evening -> night. Then each time a transition was going on i render two full size textures with gr... Continue reading

  
• angles and the great distortion
  February 21, 2025 by Bastian

  Ugh, today i found the great distortion between the physical math and the computer math. It is just the way they calculate radians and degrees. By looking at the first graph you see that angles go ant... Continue reading

  
• game making
  February 20, 2025 by Bastian

  After few days of speculating i really needed to express some techniques that i have written about here in this short devlog and put them to use. Here is a small example of how a game is developed usi... Continue reading

  
• collision
  February 16, 2025 by Bastian

  Be not worried. There are libraries which work with collision like box2D but your headache will not go away so easily anyway. Start by small steps and learn on your own how it works. Or do it like in... Continue reading
• classes and oop
  February 08, 2025 by Bastian

  The worst thing ever but also so usefull. Why do game producers need clasess and in lua? Well… there is this strange tutorial on lua pages about metatables and it has even inheritance but for some r... Continue reading
• trajectories
  February 07, 2025 by Bastian

  Today i investigated the calculation of trajectories for a simple jump like path that looks like a sin and cos half circle and a cannon ball trajectory that can handle wind. The jump was no problem to... Continue reading
• fullscreen (LÖVE2D only)
  February 05, 2025 by Bastian

  Some games need only one resolution and you want it the same no matter how the window resizes. When going into fullscreen mode the default mode in LÖVE2 D is desktop and the preset resolution changes... Continue reading
• general base of project
  February 04, 2025 by Bastian

  It is good to have some time and develop few classes that can be used between game projects. This i would recommend. main - only basic game object to run draw and update on game - the core engine that... Continue reading
• fonts
  February 01, 2025 by Bastian

  Fonts are a thing i need in almost every game made. So why is it important to keep them fast. Because they slow down the whole rendering if you do not know what to do with them. First off there are 2... Continue reading
• scaling the screen
  January 29, 2025 by Bastian

  Well, you maybe know it. After trying some small lua API you see there is no way of properly getting the game resolution to work from start. When my screen is 1900x800 pixels and the game is retro loo... Continue reading

  HOWTO SPRITE SORTING IN 2D SCREEN SPACE Hi. It is not an easy task to sort sprites so the game does not look like you draw first bottom sprites, then from right to left, then top sprites and override... Continue reading
