Asteroids movement (off screen)

[d-soldier]

Thanks for the shared experience... the problem is, most of the asteroids are not clones. Looks too obvious is each one is the same shape, spinning around at the same time, at the same frame... But it seems your first thought would work, working with a timer adjusted variable, and an "if" script... I'll work on that tomorrow...

POST EDIT:
Works like a charm! Just a simple IF variable with timer adjustment...

Is it possible to give actors a directional persuasion?.. With my radom vectors/collisions the asteroids sometimes take up a direction that keeps them either horizontal/vertical in areas at the border of the screen.. Which means you cant see them while they are there... it doesn't happen frequently, but once is enough..

you could try comparing x against xprevious and if they are the same then change the angle. then do the same with y.
if (x=xprevious) angle =angle+1;

or you could get complicated and give each asteroid a slight gravity that would cause them to not move in a straight line.

Nice! I set it on a 2 second timer, and it's small enough that you dont really notice the direction change. +1 for you!

I have these powerups appearing from a filled-region(which is on a path around the view to give a random starting position).. I want these powerups to destroy themselves when off screen (makes you rush to get them when they appear or lose your chance) but since they start outside of the view, the out-of-vision event doesn't fit... any ideas?

make an actor variable(integer) called in.
then use this code on the draw actor event,

Code: Select all

if(xscreen > 0 && yscreen > 0 && yscreen < view.height && xscreen < view.width)in = 1;

then add on the out of vision event,

Code: Select all

if(in == 1)DestroyActor("Event Actor");

Works like a charm!

Yay!
