I am a beginner like working with graphics command now i am learning particles in DBP made a intro but cannot get a good camera position for my starshower effect it looks like stars falling down and then going forward i want the cammera move forward then backword by it self if you know how please help i need a good camera command i only know how to move a camera in a circle

you will need only a picture of a star size of an icon or smaller
and a small sprite picture

i have paste source code below

For the future, try not to include ANY media if you can help it, people are much more willing to help if they can just run the code without any hassle.

I think this is what you were looking for. If you know how to move the camera in a circle, then moving it in and out should be easy to understand. You just use another angle, and sin() again...



As the angle increases, sin goes from 1 to 0 to 1 to 0 smoothly, in a sine wave (you may already know), so then if you times that by a value and add it onto the radius, you will get a smoothly increasing and decreasing radius, which results in a zooming camera. I also included wrapvalue() which wraps the angle around to 0 if it reaches 360. This stops the value getting rediculously high.

Also, in the future use "sync on" and "sync". If you use sync on, it tuns manual screen refreshing on, so the screen only refreshes when you use "sync". This can make the screen seem smoother. "sync rate" sets the maximum frames per second.

Hope I helped.

Thanks for your advice hamish and your code helped me a lot thanks
