I have a rating system from 0-5 stars, see graphic:  I need a way of algamising/combining a star graphic into one image so that I do not repeat the DrawImage command over and over. For example, instead of doing 3 calls to: I want to do this: Which will create 3 stars for me in a temporary graphic in one line. Currently I am doing this: Rather than doing this, is there some way of doing it in one call, even if it is to some kind of temporary image that holds all the stars? |

Createimage contains a "number of frames" thing. Using that, do a quick loop at the start of your program, and pop all the star images into that. Make sure it's a global, and you can just draw that one image + frame, as opposed to constantly redrawing 1/0/0/0/0 over and over.

I tried to do that once. Then I decided it would be far easier to just have 6 images.

Hi there. Do you mean, you have: 1 image that holds all images and then use the frame to show the right amount? Or do you mean: 1 temporary image that holds all images and you display parts of it? Sorry if I sound a bit confused. |

With 1 call? Perhaps something like this:  I recommend functions though!  E.g. DrawStars( x,y , numstars )

I've now resolved the problem by doing this: |

How do I create rating stars that contain both the off/on state? I am wanting to create ratings stars that have both the off/on state. See this image:  In the above image it shows 4 stars in the on state and 1 star in the off state. I have been trying for the last 2 days to recreate this with my above code and the original image posted -- but for whatever reason it does not show the off state at all. If I replace the above call with: It should show the off state, but it never does. I would like to combine the off and on state into one rating stars image. So, if it were 1 star it would show: * 0 star on/5 stars off * 1 star on/4 stars off * 2 stars on/3 stars off * 3 stars on/2 stars off * 4 stars on/1 star off * 5 stars on/0 stars off Any help on this would be great. |

Isn't this exactly what you've been trying to do the whole time?

No, apologies for the mis-understanding. Originally I was trying to just output the "on" state for the stars, but combining the "off" and "on" state looks much better. I will try the solution provided by Teasy to see if this will resolve my problem. |

I have tested Teasy's code, this gives me what I was after. Although I had a problem -- the stars are being displayed in the wrong order, the on state stars are appearing on the right hand side. I resolved this problem thusly; 1) Changing the image Teasy posted so the on state images are first 2) Adding a switch statement in the function to invert the number of stars being shown (ie: if show = 5, then show = 0,etc) Is there another way to invert the stars in their display, so that the on state stars appear on the left, and not on the right? Many thanks. |

Nah, that's pretty much how I'd do it..
