Thank you for your suggestions, they are much appreciated. I am applying the shader to a texture I have captured from drawing a combination of textures to the back buffer, so in effect a single 2D screen sized image. As I have been working only in 2D, I have only really dabbled in pixel shaders, is it possible to apply a vertex shader to a ...

Having only just started playing about with pixel shaders, and not fully understanding all the functions yet. Can someone give me a few pointers on how I can optimize the following bit of shader code. I am currently using to many arithmetic slots for shader 2.0 and I would prefer to keep to shader 2.0 if possible. The effect I am looking for is ...

Offsetting is so simple now I think about it, I was originally looking at how I could offset and got myself all tangled up with the scroll speed rather than the pixel locations. It works! I use a vector2 to hold the origin of my map, I can move the origin to scroll the map. I am able to use this vector to offset my pixel shader. I no longer ...

Ideas for naming conventions: Location: Name of the land, kingdom, domain, city game is based within. Example from current games: Albion Character: Name of the enemy, protagonist, notable NPCs. Example from current games: Super Mario Item: Name of specific special items integral to the game. Example from current game: ...

Are you running your project in Debug mode? While running in debug mode I get a regular jerky frame every few seconds but I don't get the jerky frame when I run my project as a release.

Thanks for this, I was just mulling over the idea of creating an array that represents the pixel position of each pixel within the height and width of the current map, I could then ensure that each water pixel has a static point at which to apply the sin function. So that when the map scrolls the water pixels retain their link to their position ...

My way of working has changed some what over the last couple of years, its probably my age, it's always good to set up a terms of referrence if you are going to be working as part of a team. I tend to sketch out a higher level plan, no game logic, aims, conditions and plot. I then break the higher level plan into chunks and dive into coding ...

Cheers for your response, it has helped give me some food for thought. I'm not sure how I would apply a transformation matrix to a texture, or indeed a bunch of seperate textures. I have never dabbled with those yet. Do you suggest drawing the entirity of the map with its layers and then using a transformation matrix to move it about? at ...

Background: 2D, top down RPG, TileEngine based. TileEngine handles a layer that draws water, the water has a pixel shader to make it appear to ripple. To get the ripple effect I use the follow short piece of code in my shader: Tex.y = Tex.y + (sin(sin(External-(3.142/2)-Tex.y/10)*30)*0.01); Tex.x = Tex.x + ...

Hurrah! Can't believe I missed that one! Thanks for the pointer. My brain has become mush, there are too many things I want to do with my programme. Cheers.
