Ahhh! It's the clamp thing ><.
I spawn the particles with "random" + sin/cos.
Is there any other way to spawn the particles in a circle?
Without clamp, I don't know, how to tell the Sprites to keep away from the center^^
And random picks numbers that are(sometimes) below the number "clamp" allows. That's why they get stuck at the same place and it doesn't look good. I find out what's wrong, but still wondering how to fix this.
edit: Got an idea, I'm sure Tulamide knows how to make a selfmade "random"-function. I need one where I can make random(60,120) so I get only numbers from x to y. Can I do that with expressions and events?
First of all: It was a little late last night. The method I provided for spawning at a rate does only work, if the spawn rate is at least 50% higher than the framerate. For v-synced 60 fps the spawn rate needs to be at least 90, etc. I'm sorry about that, but if you will never spawn below that threshold you can safely use such a method.
Yesterday I also started working on sprite particles to help you on this. It is not finished, but all the basics work:
It shows in particular how to work with two radii to spawn the particles on a circular band.
To get a ranged random, just add the offset and randomize the distance between the first and second value. To get a random number between and including 60 and 120: 60 + random(61)
I will now dl your cap and have a look at it. But it may take a day.
EDIT: I don't know why, but I get a 404 on your link. This happens quite often with dropbox, but only to me as it seems. :(
