I'm getting a wierd black outline on all my sprites. I can cope with it now but i'll need to eliminate it when i release my product? Anyone know whats causing this?? It keeps up even when I have Set colorkey set to 0,0,0(black).

You scaled it up massively so the outline is going to be scaled up too... The colorkey only works on colours that are exactly black, not colours that are close

I'm not sure which image format you're currently using, but, like you said, jpgs do suck. They can often create "artifacts" or incorrectly colored pixels in the image, especially around areas of contrast (the edge of a sprite). Note that if the pixels are off by one value of red, green, or blue from the color key, they are still displayed. I recommend using a simple editing tool (MS Paint or equivalent) and filling the parts you do not want visible with the color key, then saving as a format with minimal compression (BMP (24- or 32- bit), PNG (non-interlaced), TGA). Note that gifs AND jpgs are very compressed.

By the way, for best results, I highly recommend using photoshop or gimp(free) to create a sprite with a transparent component and save as a PNG or TGA (I haven't had much like with 32-bit BMPs). This can mimic glass, water, or even serve to allow a smooth, faded edge on sprites.

Imagine this: there may exist infinite parallel universes, all similar to ours, but we may never be able to encounter or even interact with them.

I think Diggsey is right.Try to make your images in your paint program bigger so you don`t need to scale them.Then the line wont bother you.

There is no scaling........and there is no outline in the original .png. Just red.

I'm serious. the reason that the two sprites are differant is because well, i took a screenshot in Db, and Db blew it up to match the screen size(640x480). Then it was incredibly smaller in paint............

I think that`s exactly why most games have diferent textures and sprites for diferent resolutions, so they can match the screen size without problem.

Why don't you change the screen size/resolution?

Seeming since you have been here since 2007 I assume you know how but just in case the code is below.

It looks like to me that you're not using a ,1 at the end of LOAD IMAGE. When you don't use a texture flag of 1 the image is blurred.
