Destructable maps idea!

Hi!

The 1st thing I thought cube engine could be able to do, was to make it easier to implement destructable maps.

I mean, each shot or explosion or hack&slash, could destroy a certain ammount of the map (wall, floor etc).

That shot would leave a hole in a wall for example, and the same volume of the hole would be spawned in small debris cubes that would become dynamic and fall to the ground with physics.
And when it stops, then those debris would be reintegrated to the map structure re-becoming static again.

The problem is, I have no idea where to start coding it, but I am sure the most important thing the cube engine already have, cubes!!!

So I put this ideia to anyone willing to implement it. Unfortunately I am not being able to have time to implement it :/

hi demosthenes,

My answer #13 covers most of what u said.
I just would like to add that my ideal of a map is a random map, a never boring map, a map were there is always something new to discover.
Not a silly but a well thought random map, with convincing results!

Yep, map makers now will get scared, I know ^^...

Have u ever played a game called Mount&Blade?
The 3D battle zone is randomly generated, the trees and mountains and water.
Ok it is simple, no random houses, no random fortress, no random paths between towns, no towns! I dont even remember of rocks on the floor! no random dungeons... no dungeons at all hehe.
Btw also, check for DungeonKeeper2, at the automatic map digging/created by the AI.

What I mean? if there are well planed rules, if you have a good map generating AI basis, a random map can be convincing and fun!

The only problem about this? this doesnt exist... yet! xD

you could probably set something up where the lightmaps were essentially slices, and then averaged together in the engine, but they'd be blurry as hell and almost totally inaccurate. What's the point?

I still put those ideas to anyone that may be inspired on them to create their own solutions :)

I mean it, I have too little time, I code all the day at my job, so at home I have little brain cells willing to code a bit more.

I will probably code a bit, and some other time code a bit more, but I dont expect that to go much far away from that... ^^, cuz of that I was looking for a script way (portable thru versions) solution, so I could easy it up.

PS.: mmm... unless if I win lottery! XD

Why not split the difference and add the ability for the map maker to make certain cubes destructible, and in predictable ways?

Sorry for the newb mapper question, but "wall" mapmodels and barrels work in MP?

No. There was extensive discussion of that previously, if you care to look it up.

I recall reading that extensive discussion. #10 started discussing destructibles in MP and so the suggestion after that point in the thread to use mapmodels made me wonder if I had missed some new development. Apparently half the posters on this thread are talking about SP and the others, MP.

I could have been more clear in #18 that I was talking about MP. That post was also aimed rhetorically at the OP to some degree (ie - why make everything destructible when it ruins maps).

Gosh, the intarwebs foster such great communication and cheer! :-]

It can be done in MP too, and the beginnings of that is already in Blood Frontier's SVN with doors. With recent developments the point is moot anyway.

If the destructible mapmodels were part of mp, then you could just use mapmodels that explode. If you try for anything besides that, I think you'll never get it to look correct. Do you know how long it takes to compile lightmaps? WAY too long to be thinking of doing it during game play.

On the other hand, it might be feasible in cube1, as it doesn't use lightmaps....but it's still just a silly gimmick IMHO.

Very true. A game needs to be designed from the ground up, ie as (an integral) part of its gameplay philosophy, to include destructible geometry, else it's just a 'gimmick,' like you said.

Well yeah, that *is* what *I* was talking about in the first place. Models just offer more in terms of destruction and dynamic state control. You can always have dynamic shadows for them too.

#27: I might be interested in this project

by Hypocorism on 06/19/2009 10:10

I\'m interested in seeing the destructible terrain come into play because there currently exists no (good) sandbox MMORPG. Wurm comes close, but the combat is significantly flawed and no fun. If, as you have said, the light mapping is not a problem in Cube 1, then this would be a good place to start. I\'m interested in putting significant work into getting a mod working where you can destroy parts of the environment. (IE, chop down a tree with an axe, break apart a door, dig a tunnel with a pickaxe/shotgun/whatever). I can do code and also some texturing. I don\'t need to lead the project, I\'d be happy working with someone with the whole destructible terrain vision. We can try to solve the problems inherent as they arise.

#28: Researched a bit, have a question

by Hypocorism on 06/19/2009 10:42

I've just been playing around with Cube 1 and the lighting doesn't seem to be affected in the same way when you make adjustments. The lighting still looks good in that game. How do the 2 lighting systems differ? Shouldn't it be possible to roll back features of Cube 2 to use Cube 1's lighting system?
Funny stuff with the for loop joke, demosthenes. I didn't see this thread before I posted. I'll look closer next time.

Programming is not plug and play like lego. Cube 1 and 2 are very very different creatures - Cube 1 regenerates the geometry on every frame, horrendous but it worked as the maps (and lighting) are 2D-ish... Cube 2 is true 3D, the geometry is basically cached and all lighting is pre-rendered so it still achieves goo d performance.

#30: heres another idea.

by |ice|sub-zero|L on 06/20/2009 03:33

instead of the ground, what about glass, in this game it won't break, how about it does, but it'll come back after a certan amount of time?

#31: Thanks for the feedback

by Hypocorism on 06/22/2009 11:21

That makes a lot of sense. I did get the impression that cube 1 maps are more like the doom wads of yore. For what I\'m thinking of, it would have to be cube 2. I don\'t think you could achieve a realistic effect when you cut down a tree in cube 1. As for the lighting, it\'s not really that important. How about just pulling the current lighting system and have levels of darkness be generated by height from the ceiling?
For example, if you\'re out in the sun, everything would be full bright. Dig a tunnel into the ground, and it starts getting darker. Of course, you\'d have to have something like, if there is a 1 meter hole, get darker as you go down. If there is a 1000 meter hole, stay full bright. You could regulate brightness and darkness based on the rising of the sun and moon. The lighting doesn\'t have to be perfect.
I think I also solved the map breaking difficulty. Regulate the size of the cubes to make maps so that they\'re all the same, and only destroy sections based on that cube size. Map breaking and jagged edges happen because people use cubes of different sizes incorrectly right?

by tentus_ on 06/22/2009 13:32, refers to #31

It's good that you're trying to think of solutions, but you're off the wrong path. Regulating the cube size (if I'm understanding you correctly) wouldn't do anything. As the engine currently is, I'm not aware of a way you can modify a cube "incorrectly" as you put it: the worst that you can do is let water materials touch the edge of a map. Everything else, even if it's ugly, is valid.

The problem is that a big change, like your lighting hack, would create version problems with old maps that *do* care about pretty lighting and 3D lighting (hint: almost all of them). Lighting is crucial to making an appealing map, so any big change to the way that lighting works means that all the old maps are left out in the cold.

#33: red faction: worth looking at

by freckletoe on 06/24/2009 02:15, refers to #32

so there was this old game (2001 is old now? idk) called red faction (1 & 2) not the newest one, but anyway they're physics engine (geomod 1.0) does pretty much just what you're talking about. Maybe worth checking out for ideas.

#34: destructable wall

by Marwo on 07/07/2009 15:14

hmm, since sauerbraten already have the edit in-game function and you can push the face of a cube and shape it, maybe its possible to for example:
The mapper can make a wall/cubes that is marked as "destructable" and when.. lets say a rocket/exblowtion hit the wall the wall will recive the damage acount on eatch cube and apply the amount of "face of cube pushed in" (depending on how mutch damage the cube recived). Kind of like freckletoe sayd about red faction, it has that kind of similar system.
and about the pre rendered light, maybe make the destructable wall fullbright or somehow make the wall show a brightness that is the same as the average brightness of the surounding?
Or maybe it is possible to have the wall rendered with, lets say 20 different ways and the wall can be smashed down with 20 rockets. an example: 1st wall model is a healthy wall with no damage and with its own prerendered light, second wall is a slightly damaged wall with its own prerendered light... and so on.
Im not a programer, but im just throwing in whats on my mind. :)
