Re: graphics and maths formulae
Hi,
The good news is Allegro has some spline functions which can
fairly easily create smooth projection paths.
There is an example program in Allegro which allows the user
to create a number of dots on the screen and when the user
presses esc or space or something, a larger dot travels through
all the points you clicked on using a smooth path.
The bad news is I haven't wrapped those functions in euAllegro,
and don't know how difficult it would be.
If you wanted to use euAllegro you could probably talk me into
wrapping the functions.
Another option, (note that I have never done anything like this)
... but if they are going to use preset paths (like Galaga)
you could just create sequences with the (x,y) values of the
exact path.
Then use the current (x,y) value of each invader to create
the correct offset.
This obviously would only be useful for preset paths.
You might like to ask your question on the newsgroup:
comp.games.development.programming.misc, or
comp.games.development.programming.algorithms
For some more ideas.
