Default Object Impact - 09-21-2010, 05:11 PM

How would I make an object fall on its side when another object hits it? Like if I were making a shooting game and when I clicked an object the bullet would move toward it and when it touches it the other object falls over.

There are many examples of this in the forums, but the easiest way is to make an actual bullet, and and put in an event saying "While(bullet) is within 2 meters of (enemy)", "enemy turn backwards 0.25 revolutions". This however is not the most accurate way to do it because you might be able to aim next to the person and still have it count as a hit. For a beginner programmer though, I recommend using the code I just said.

If you feel you know a little more about Alice and you are able to understand more complex code, you can check out any of the gun games made here on the forums, I know that Debussybunny just made a new gun game with a good way of detecting bullets. Also, I am going to finish my Sniper example in a few days hopefully which should provide a fairly accurate bullet collision example.


Check out my best projects so far and please comment:

See here: Bullet Collision

EDIT: A tip if you're going to use Dameria's first example: Don't make the bullet move too fast (i.e. 1000 meters in 0.1 seconds-never use zero for the duration, it will probably never register a hit) , or it will be less likely to detect. Experiment around to see what works best-if you want a rapid fire rate, balance it with a slow enough bullet speed.
One workaround is to make several bullets, each bullet itself moving at a slow speed, but when you put one after another in rapid succession, it seems quick.

I have been dead for quite some time now; not much hope for resurrection.
