So I was wondering if there was a way to keep a particle under a moving entity;


For example; I have fire that pushes out the bottom of my entity, which should look like its a jet pack.

But when the entity moves, the particles stay were they were created, leaving a trail of fire behind.

If any more details are required, just let me know.

thanks,
Devon.

You can try something like this:

vec_set(temp,my.x);
c_move(me,...)
vec_sub(temp,my.x);
vec_scale(temp,-1); //facing in the wrong direction

effect(..., temp);

The particles now have the velocity from your entity. This may lead to weird looking results when changing the entity's direction, though.
Instead I would try to keep the particle's lifespan really short.
