Post subject:  MOSParticle Animation Problem
Well, i've stumbled onto a problem which i do not know what to do.
Whatever i do, the animation on a MOSParticle is fixed, even if i put

SpriteAnimMode = 1
SpriteAnimDUration = [100,200,600,10000, Doesn't seem to make a difference.]


Any Suggestions?

MOSParticles are terrible at animating. They are hardcoded (as near as I can tell) to animate across lifetime.

Believe me, I've even tried to get them to animate using forced lua code, and it just doesn't happen.

While this THEORETICAL method might not work and will most definitely lag, you could try making a lua script that analyzes the MOSParticle's last velocity and position, and then swaps it out with a different particle (the next stage in the animation) of the same velocity at the same position as the last one, but to simply do this over time intervals.

Just a thought...

EDIT: I actually think I'm going to try that now, that sounds intriguing!

Actually, that's, uh, not a bad idea, Joe.

You could do it in a much simpler way with mostly .ini; just have the particles gib into the next frame with inheritsvel with no added velocity. Then use a lua based timer to force gib after the correct time delay.

wouldn't it be just as easy to have a MOSR with GetsHitByMOs off and a custom 1px atom? you could keep it constantly oriented vertically with some easy lua.

Yeah, but MOSRs can't glow.

And how would you add a color changing trail to an MOSR? Correct me if I'm wrong, but you can't actually attach a MOPixel to an MOSR, simply have them emitted/created at the same time and place.

I somewhat got it working. Pass this along and see how it can be improved.

Thanks for the replies, looks like i'll have to do it with lua.

You can have trails on MOSParticles now? Or am I missing something crucial about the requirements of this's implementation. If you needed glows you could use an AEmitter instead of a straight MOSR, and have the glow on the flash, or do the boring old "glue a nothitting veryshortlifetime glow to yourself and have its age reset each frame". I'm not saying the recreating MOSParticles thing is invalid, I'm just wondering why being able to do self.Frame = and have is work is less crucial than glows and trails (do they work? cause setting the trail on atoms in an atomgroup doesnt work..)

This is pretty obvious self-promotion, but I made a simple framework-y thing for animating things by swapping through things you spawn. I wanted to animate glows, so that's what it does -- this is pretty intensive at it turns out, so it can look jagged when in motion or on a slower machine.

I hope that's even moderately helpful.

Ok since Grif said Lifetime, I'm assuming he meant the variable which dictates how long it stays.
Upon experimenting, I decided a 1000 lifetime would be suitable. However it was still a little slow.
So, i tried adding around 6 more frames, and luckily, it worked at an adequate speed.

Thanks guys.

i was just thinking about doing that with glows in English class today!
