# Grow :: procedural generator  by eppo

Time Spent: -
Date Added: Jan 15 2013 08:42 AM

Content (terrain, buildings, foliage) generated with my procedural tools.

I wanted to simplify my game's collision system at run time by using only a single type of collision shape, namely convex hulls. Because manual hull construction puts a lot more pressure on the content generation side, I've tried to automate the process as much as possible. All tools now create a convex representation in addition to their main geometric output (see video).

Wow, this is seriously impressive work, how long have you been developing Grow?

Keep up the amazing work.

Really cool!

awesome work!

Love the style and lighting of those screenshots. Especially love the one with the sci-fi looking turrets on the ground. I want to play that game.

It looks fantastic!

Wow. Beautiful work.

look sooo great !!!!!

Looks very nice. I like that you made this publicly available. But I can't get it to work. Running PHP 5.3.3 on WAMP.

I tried to run the main script or the other scripts, and I get this error on gen/gen.php:

Parse error: syntax error, unexpected '[' in ... \gen\gen.php on line 21

It doesn't seem to like this array element: stream("lxosaver", $options)["data"] it's terrific Very nice looking! Do you have more information on the rendering engine? I checked the above error, and apparently dereferencing an array returned by a function, 'a()[]', is only supported in PHP >= 5.4. Sorry about that. These are the dev-tools as I use them myself. I've found it's very well possible to set up a custom tool chain without a graphical interface to support it. It's not the most intuitive way to have to modify tool arguments in a script file, but it allows you to focus purely on the algorithmic implementation. Especially scripting languages are very useful to serve as a 'programmable interface'. e.g. instead of spending a month writing a full blown curve editor, I can get away with a simple spline class:$options["tree_roll"] = new Spline(0.2, 0.5, 0.4);

Super!

I have seen a few Activison's games for children (Bee Movie, etc.)

This game would be better...

Very impressive graphics. Good job.

You should use <?PHP instead of <? for better compatibility

Neat tools. If you're interested in getting some more users, then better documentation of how to use the tools outside of your PHP management system would be welcome

Superb!

eppo, thanks for checking out the error. Looks like I'll upgrade my PHP just to use this, it looks like a real timesaver for making levels. I also second Giallanon's suggestion on the opening tags. <? is less safe and not as likely that all server configs will support it. Fortunately I caught this and changed all the tags.

Very nice!

I'm going to start posting details on the engine's features in a journal as I add them.

better documentation of how to use the tools outside of your PHP management system would be welcome

True, but at this point I've chosen to focus primarily on the game itself and can provide the toolset mostly only 'as is' (I've changed all the '<?'s into '<?php' though). I'm fine with how it works myself, but I've forever had this user-friendlier GUI concept laying around, which I'd like to implement one day.

Wow cool, is it writen in PHP ??

The boots seem like out from different universe and kinda ruins the character, i suggest going with something more cute/toyish, not with boots like that
