How do I create a particle effect in the opposite direction?

Hi,

I've created a particle effect to show a thrust motion of a flying saucer on drag and drop. However, I'm unsure how I make the particle cone match the opposite direction in which I'm dragging, thus showing the thrust pushing the saucer along.

Any ideas please ?

Many thanks for any help you can offer me.

This might not be the best way to do this, but out of my head, i would make this:

every 0.1 sec while dragging: store the X and Y of the sources in instance variables.

and set the particle effect angle to the angle between the stored coordinates and the current coordinates.

Thanks for your help Sargas, but I managed to find the solution on the forums - Sorry, for some reason I couldn't see it yesterday.

The answer is here :

In essence : (180+saucer.Angle)%360

Cheers all.

Doh ! No it isn't, as the angle never changes on drag. Back to square one, but I'll try Sargas' approach now.....

huehue, yeah, i knew the angle of the object wouldn't change, that's why I though of my system ^^

here, i had some time in my hand and made it for you =)

I made a little different than I initially though, this works better =)

Absolutely fantastic - Thanks so much for the effort you put in on this Sargas - It is very much appreciated.

Cheers

Sargas yep pretty cool I like it thanks
