[resolved?] SDL_WarpMouse supresses SDL_MOUSEMOTION events when a button is held?
|
So, I have a fairly standard control scheme with a peculiar problem. In the Event loop, I check for mouse motion like this:
case SDL_MOUSEMOTION:
mouse_x = event.motion.x; mouse_y = event.motion.y;
break;
And in my game code, I... |

Soup du Jour

Hello, my fellow Gamedev members! I and my friends have just finished a game that evolved from a little Verlet physics demo I wrote for fun and posted on the forums almost two years ago. The end result is perhaps the most rubbery match-the-color... |

2d physics experiment
|
I was a bit bored the other day and decided to write a little 2d "Verlet" engine. :) Its core is more or less based on the "advanced character physics" paper although the collision detection system with convex multi-particle objects is my own.

Creating an SDL window centered on screen
|
I'm making a "launcher window" to set videomodes and such for a game... One thing that kind of annoys me is that it's showing up in the top left corner instead of center. Also, I can't figure out if it's possible to make a borderless window that... |

Adding ambient term to ARB_texture_env_dot3?
|
I'm trying to figure out how to add a bit of ambient to my landscape that's lit by normal mapping. The normals are in world space so I only need to set glColor once for the directional sunlight. Unfortunately, there's no "dot4" so I can't just use al... |

How to query desktop resolution for SDL/OpenGL?

I can’t find anything particularly useful on google, apart from the fact that GLUT fullscreen mode will default to current resolution. Is there a portable way to just query the current screen resolution in SDL, or do you use system-specifi... |

Is there glTexGen equivalent for GL_EXT_fog_coord?
|
As the subject goes.. Is there a way to generate fog coordinates (for GL_EXT_fog_coord) the same way you can generate texture coordinates from the vertex coordinates? |

stencil buffer problem on GF4MX440

I’m using stencil buffer to draw sky gradient behind my landscape... In the beginning of each frame I call glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT | GL_STENCIL_BUFFER_BIT); Then I draw the terrain, writing 1’s to the stencil bu... |

Unusual VBO slowdown

I implemented vertex arrays and VBO in my planet generator experiment... To my great surprise, VBO is performing much slower than regular vertex array, and even slower than immediate mode. The polygons are divided into 20 batches (there are 20 unique... |

VBO based GUI
|
I would recommend Vertex Array as the first step. It's simpler to deal with than VBO (because you're just keeping an array of vertex data in RAM) and should be available in all flavors of OpenGL including ES. The performance differences between the d... |

Looking for a 3D model format

Blender's .obj exporter is actually nice, it lets you specify exactly what information you want to export. Assuming you've created a model that has per-vertex normals, just make sure the "normals" button is pressed in the dialog that pops up when you... |

Yaw + Pitch = Roll

This is correct, desirable behavior. A real spaceship or plane will do the same thing. Any attempt to "fix" it with Euler angles etc will result in unrealistic and annoying gimbal lock behavior.
Consider the case of the plane pitching up 90 degre... |

Defining a "nebula"

Your example implementation produces a fuzzy sphere that can be used as a building block for nebulae although you may want to modify the attenuation function so that the center isn't a sharp point.
To build a nebula you start by making one su... |

engine for big big map

Verlet constraint confusion

Best multi-platform gamepad support?
|
I included basic joystick/gamepad support in Brainpipe, also written in SDL. This is more or less the bare minimum you'll need:
1. (Using a mouse interface) the user picks the joystick/pad from a list.
2. Before setting up anything else, the pl... |

problem with 2D zoom
|
If you're using texture clamping (GL_CLAMP), try using GL_CLAMP_TO_EDGE instead. This will prevent the border color from showing up. |
