Hi,
im working on a platforming game and i want to make the enemies drop a few coins when they die.
i'd like them to bounce around a little bit before stopping, so they might hit a wall or a ceiling a couple of times.
problem is, im not sure how to make a really simple collision system for these coins.
the one im using for the character is quite complex and im not sure i can replicate that same system for each coin.
any help will be greatly appreciated.

if you're desperate there's always the pinball movement, although they might get stuck in walls and stuff occasionally.

The best would be the embedded collision detector system. basically, you have a bonus animation on your coin, and in the 4 directions you put a block, pixel, line, which ever you want which is paced at the left, top, bottom and right side of the coin (relative to the hotspot). Then, you do:
*always
-coin animation = collision
-coin direction = right
*coin is overlapping backdrop?
+coin is moving right
-bounce left
*always
-coin direction = down
*coin is overlapping backdrop?
+coin is moving down
-bounce up
*always
-coin direction = left
*coin is overlapping backdrop?
+coin is moving left
-bounce right
*always
-coin direction = up
*coin is overlapping backdrop?
+coin is moving up
-bounce down
*always
-coin animation = coin
So it flicks through each of the collision frames and checks them against the background.

Here you get an example that I make, I do not understand very well because the English is not my original language. I hope that whatever you ask.

Obviously the simplest solution from a coding point of view, but as Mr Pineapple said, coins might get stuck in walls with pinball movement, the collision detector method is pretty much a lot safer.
Although, this in itself could be considered a very minor issue, so if you don't want to go into things like the static engine and want to use default movements, Sergio's example is best. Mine is more suited to Static movement engines (i.e. custom position setting etc.)

Pinball Movement Works! Set the speed low and default moving upwards. Then add an event that
+Alterable Value A of Coin<5
+coin collision with Backdrop
Then
Coin-> Bounce
Coin-> Add 1 to Alterable Value A
+Alterable Value A of Coin=5
+coin collision with Backdrop
Coin-> Bounce
Coin-> Stop
Simple!

sorry MrMcFlurry, do you mind making an example ?
i tried to do it, but the coin keeps flashing as it goes through the bonus animations.

Here ya go, a small static engine, random obect selection on killing an enemy included too. The code also shows a fix for the animation problem embedded collision detectors causes (i.e. repeatedly stopping and starting the animation effectively freezes it on the first frame)
Though, an alternative method isto simply use an external detector, but that would require a loop. This is the simplest and quickest static engine method for multiple, single animation objects such as this that i can think of.
Although, if you aren't using a static engine, I would suggest going with the example sergio gave using the in built pinball movement.

If you look on sites like Sonic Fangames HQ, they defiantly have some very interesting tutorials that can help bridge the gap between simple tactics and more fun to work with techniques. For example, you could probably come up with a very interesting coin drop system by learning how to create proper ring spills off of one of their tutorials. Making a fangame may not be an accepted thing to do, especially around communities, however the knowledge you gain by trying to reproduce a professionals work, is generally priceless knowledge you wont miss having.

Haha! I thought sonic fangames hq was long dead! It even still has the faster running method i did like, 8 years ago! Just when i was beginning to experiment with the static engine concept  (http://www.sonicfangameshq.com/view.php?sec=4&id=7 lol)
Thanks for making me look it up
