directX10 - how on earth do you vsync?
|
I'm slowly making the switch to directX10 by re-writing a simple enough 2D game from scratch for it. Seems pretty nice so far, a lot of the fluff has been tidied up etc.
But one thing which is really baffling me is how to enable vsync.

Objective C - is it possible to create object arrays?

Hi,
Not sure how many Object C programmers we have here but I've started to learn it and have run into a problem.
I was using structs and arrays, but want to migrate them into class's and objects. So I've got my entity struct and moved it into... |

Calculating rotation from movement.
|
Hi,
I hope someone can help. I'm coding an iPhone game and I'm trying to calculate the rotation based on the speed of an entity (x and y).
Normally I'd get the speed, then calculate the rotation using cos and sin. But now I have the x and... |

Dissecting Sprites in DirectX9

Hi everybody,
I'm currently working on a 2d game engine which is going to have some obscenely large sprites, and the problem I've ran into is that directx has a texture size limit (depending on the graphics card) where as a surface, can... |

Thanks for all your help so far, I'm slowly getting everything put together for a basic RTS game engine. height mapped terrain with real-time deformations, (crude atm) multi-texturing, projectile physics, terrain following for wheeled vehicles and th... |

Directx sizes and scales (where to start)

I'm sure this question must have been asked before but my search skills are failing me.
When I first started working on my directx projects I used an .x file exporter for 3dsmax, the result was that a pretty large model in max ended up at aro... |

Finding out where a ray hits the ground.
|
Hello again chaps,
I've implemented a picking system where I can select my little tanks by clicking the screen, which creates a ray then performs an D3DXIntersect on all the tanks and selects any which are clicked on. Nice and easy!
I... |

(looking for) a shader for blending textures together

Hi everyone.
Can anybody recommend to me, or tell me the source for a good shader for blending multiple textures together?
I've made a landscape from a height map and just wanted a shader could take 4 different textures, and depending on... |

Direct-X 9 mouse problems

I followed the directx 8 mouse tutorial on the site and it all compiles perfectly, only the mouse position always seems to be off.
I've created a mouse_x and mouse_y variable at start-up, and then everytime it calls the GetDeviceState I... |

Aligning an object to the level of the ground beneath it

Hi Chaps,
I need some help again, I've written a bit of code which fetchs the heights along the middle of each side of an objects bounding box, then uses this to calculate the roll and pitch in order to make the object 'sit' on the landscape... |

Dissecting Sprites in Direct3D

Trying to port this across to directx9, it all seems to run perfectly but I only get the first sprite which is just a black empty box.
Any ideas? replaced my old 2D sprite loading code with it as it made more sense (some of my sprite sheets a... |

Thanks.
My plan is to get all the basics done then optimize it like crazy before moving onto anything else. Just need to figure out this selecting a spot on terrain (threads in general game programming) then I can start optimizing what's... |

Finding out where a ray hits the ground.

Bumpity!
Managed to convert my whole terrain system so it produces a mesh which is now rendering perfectly, hurrar!
So I've started using the D3DXIntersect system, assuming the U and V values it spits out would be relative to the object space c... |

Finding out where a ray hits the ground.

Thanks for the source, i'll give it a shot.
The reason I can do it with the entity models are because they are mesh's loaded from x files. I tried converting my terrain into a mesh (creating a mesh, setting the FVF, copying the vertex's across etc... |

Your a star!
I'll give it a try next time I'm coding and let you know how I get on.
Whats the best way of getting the blend %'s to the shader? My thought was to have a vector4 storing the 4 blend values inside of the FVF. But does that wo... |

Thats what my first thought was, but i'm pretty new to C++ and my engine is a frankenstein of tutorials merged together :) Could somebody be so kind as to set me off in the right direction as to how I do it? |

Thanks for the reply.
I wouldn't know the "appropriate quads" as I don't have the X or Z values either :(
I followed this tutorial to do the object picking:

If you just apply the transformation matrix on the AABB, it may no longer be an AABB.
Hmm.. The axis alignment basically just changes the rotation.x and rotation.y values for the entity, so that sort of gets f... |

Thanks for the reply.
I must not have been too clear, but it sounds like I was doing the bounding box stuff the right way.
Basically everytime the entity moves, it recalculates it's own bounding box by getting the meshs boundingbox (which never... |
