Many questions

Hi all.

I have a few questions, and thought I'd compile them to a list rather then spamming the dev list loads. If I get an answer others may have use for, I can post that as a separate entry later.

OK, let's go.

1 > Let's say I have a sprite moving around using two random nodes, one for X and one for Y, possibly also one for Z but I doubt it. I would like to orient the sprite to the direction it travels. In other words, can I have something with a 'front' move 'forwards'?

2 > Creating trails that fade. Is this possible? I thought it may be if I used the Replicate in Time patch, but can't seem to get it working. Imagine a sprite moving around, I'd like to be able to set a length and have a tail emit to that length.

3 > Enabling with Audio. I'd like to have sprites turn on (Enable) when a certain input level on the audio input node is achieved. I can't figure this one out, I've tried everything I can think of with ranges, multiplexer etc. No joy.

4 > Gravity, or attraction. Is this in any way possible, even as a fake? Let's say I have some sprites, I want them to slowly move together over time. Or have some sprites move toward something else, I'm not fussed what. Basically, can one thing attract another?

5 > Hold and move. Imagine a sprite, it moves to a random point slowly, then pauses for 2-3 seconds, then moves to another random point, this continues. I can get it all working, but can't get the pause/hold part working.

Many thanks for looking through this, and thanks on advance for any/ all help.

Regards.

Andrew.
