SPIKES

Buzzsaw Spike- Destroys anything except Powerboxes and Terrain
Acid- Destroys anything on it except from steel/strong things.
Lava- Destroys anything wooden on it.

TILES

Glass Tile- Acts like a steel crate, but is destroyed when it falls too far.
Ice Terrain- Less friction on the tile.

DYNAMITE

Bombs- Acts like steel dynamite, but explodes when it hits something solid after falling.
Bomby Enemy- Enemy that explodes when hit with something.

ARROWS

Flaming Arrow- Just carries on after destroying wooden objects.

we came up with a pretty cool system of tiles to match many of these ideas. The tiles are divided in classes:

Wooden - similar to HATPC wooden tiles
Steel- similar to HATPC steel tiles
Fragile- like wooden tiles, but when you break them, there's no kickback/rebound. Also, if an arrow hits it, it destroys it but keeps going straight through. And if something solid falls on top of it, it destroys it and keeps going straight through it. And if a fragile crate falls on top of a spike, the spike destroys the crate.
Indestructible - like a super-strong steel crate, except that if you have an indestructible arrow crate, for example, whenever it gets hit, it fires the arrow, but the crate is still there, so that you can use it again and again to fire more and more arrows.

What if fragile falls on fragile? Do they both break?

the glass tiles could be a cool idea, imo. suppose you have a glass box or something in Y-coordinate of 12. so, when it falls to 6, it breaks; if it falls to 10 for example, and then to 6, it'll be semi-broken when it's at the 10(acts the same as regular, looks alittle broken), etc. water will make any fall appear like a one-tile fall, so in water you can practically fall as much as you want in one go, but you can only stop 6 times. each time will have a different look... you get what i'm saying?

also, if something falls on it, it'll also decrease its look. it's as if the block has a health of 6; when it falls 1 tile, it loses 1 health, when it falls 2 it loses 2 etc. if a metal falls on it, it'll lose 1 more, if a metal falls on the metal, it'll lose another; so that if 6 things stack on top of it, it breaks. dynamites and arrows can make damage to it, but in proportion, as in, an arrow hits it will make it lose 3 health when a dynamite will make it completely be destroyed and stuff. when it falls on a spike it'll lsoe 2 extra health and break the spike or something...you get the idea.

since this topic is about random ideas, here are some more -
tiles with holes:
suppose you have a metal crate, which is more like a metal pipe inside a hollow metal crate. then, things can get through(as in, arrows, certain characters, etc - it's like armin's ice, but with the arrow-extension).
it should look like that: (quote me to see what i mean, cuz i suck in code-drawing)

next idea - holds in the ground
stuff like this - imagine this is our terrain
-----_----

so that if a boulder gets to the _ area, it can't be pushed out. it's as simple as that. other than that, it works just like a regular boulder.


EDIT: livio, try to edit this post and preview it, so that you'll see a bug in our previews!

lol the bug is that the spoiler tag doesn't break when you put code tags inside it?? that's just weird...

a pipe tile is a really cool idea. it'd be perfect for trapping a player in a specific area while arrows come in from all directions. What if there was a "pipe corner" tile, so that if an arrow flies in from one side, it comes out the side, but in a different direction. You could then connect two them to make an arrow U-turn, so that you could make a few arrows constantly flying around in a specific area. And then, we could also have a specific character with the ability of going through those pipes...

Agile characters should be able to go though pipes; especially Jean, as cats are small and can fit though small places; though the mouse should also be able to do it.
