Simple Platforming Programming
|
Hey all,
Looking for some advice on approaches to coding a platformer in 3D.
I have a full rendering engine and use PhysX well...just looking to hear what other people say works, does not work etc. before I start.
Any help is appreciated!... |

DirectSound issue

hey all
i have an annoying problem i can't seem to figure out:
i am using DirectSound to play back sound effects. Everything
works fine, but when sounds play, and the app isn't the focus,
when you switch the app to being the focus, the sounds... |

Direct Input Right Analog Stick

Hey all,
Trying to make my game a bit better by allowing for configurable controls
so users can remap buttons, and non-standard controllers can actually play
the game (originally hard-coded for XBox 360 controller).
I'm seeing that on th... |

hey all
got a decent heat shimmer going on in my engine.
i'm using the same map that stores the view depth for storing
which pixels are perturbed from shimmer.
depth is in x, shimmer is in y.
works fine.
when i enable alpha blend... |

Can't run Debug builds missing .dlls

Hey all
I need my artists to be able to run the debug version of my Visual Studio app for
various reasons. Some of them are missing the required .dlls, and can only run the
Release builds.
Is there some easy way to get the .dlls they ne... |

Threaded Texture Loading

Hey All
I'm loading textures on a thread using D3DXCreateTextureFromFileEx().
When the thread completes, I need to swap textures.
I'm doing it like this:
pOldTexture->Release();
pOldTexture = pNewTexture;
This works great, exc... |

PhysX actors without shapes
|
Hey all
For organizational reasons, I want to create an actor in PhysX without shapes, then add shapes later, but createActor() fails if the ActorDesc has no shapes added (ActorDesc.shapes.pushBack ( &ShapeDesc ) is never called);
Is there a wa... |

Transform mouse into 2D quad
|
dumb question...
can someone post the proper way to transform the mouse position into the space of a 2D quad that's rotated, so you can detect if the mouse is inside the rotated quad? |

[HLSL] Moving transformed vertices in vertexshader
|
Are your vertices in 2D or 3D? It looks like 3D.
How are your vertices already transformed?
Typically, you have vertices of a model in local space.
To get them to screen space, it a matrix multiply for
each local vertex by the concatenated wo... |

instance technique using dx9
|
My heroic efforts were to avoid making many DrawPrimitive() calls on things with only a few vertices for performance reasons. The meshes I instanced only had one subset.
Your needs may be different here. If your shader has a pr... |

instance technique using dx9

LPD3DXMESH sucks and will be a problem for you as long as you use it, but when I used to use it, here's how I instanced.
I needed to render many small meshes and wanted to minimize Draw() calls, so i built a super mesh by going though the vertices... |

First of all, you need to consider elapsed time here.
velocity-= .0003; will yield different results under different frame rates.
The way I handle simple jumping is essentially like this:
1.) detect user has pushed the jump key.
2.) if... |

When using two IndexedBuffers how do you reuse a VertexBuffer?
|
if( FAILED( d3d9VertexBuffer->Lock( 0, 0, ( void** )&pIndices, D3DLOCK_DISCARD ) ) )
you realize you are getting a pointer to the vertex buffer back in pIndices here right? You probably mean to do this
if( FAILED( d3d9VertexBuffer->Lock... |

Blend Modes - Writing Alpha to a texture

can you visualize the texture you've written the collision info to?
texture a 2d quad with it...what's it look like?
here's something that got me a while ago; not sure if it's related but
when writing to textures, make sure you enable alpha.

Textured Quads Particle System
|
You're going to need each quad to be made of 6 vertices, because the system is going to need to be drawn as a triangle list.
If I were you, I wouldn't update the list in real time at all...let the shader move the points around it. Build the vertic... |

Physx tutorials?

Well, that sounds good in theory, but in reality the visual debugger is broken and crashes if you have more than a few things going on. Also, you cannot easily compare your game objects to PhysX objects.
IMO, it's better to simply retrieve th... |

Physx tutorials?

I would start by wrapping the actors and shapes in PhysX with your own simple game object types. Only deal with rigid bodies to start.
Also, you need to see the debug renderable from PhysX IMMEDIATELY, as well as in your game engine. Until yo... |

why add it as a resource?
anyway, can't you just right click on resource->add->existing item->shader.fx? |
