When i try to start up the server I get this error: LUBE.lua:303: attempt to index local 'self' (a number value) Stack traceback: LUBE.lua:303: in function 'Init' main.lua:20: in function <main.lua:18> main.lua:20 being "lube.server.Init(8118)" I've tried using all sorts of port numbers, I...

Hi bartbes and everyone,

I've been trying to learn how to use LUBE so I can make my games multiplayer, I'm not finding it very easy, the docs on the wiki don't enlighten me much. Are there any tutorials around, or does anyone care to throw one together?

Cheers.

I appear to have solved my problem now. It was to do with using sensors to destroy objects. I suspect that theres some sort of overlap between the object actually being destroyed and the collision trigger being called for a second time, somehow, so it was trying to destroy an already destroyed objec...

Hey everyone, I've programmed a game that makes use of box2d physics, it seems to work nicely for a while, not getting any errors, BUT it randomly crashes--the window just closes suddenly. Objects are being created and destroyed approximately every second but theres hardly ever more than 2 objects i...

You can always just nil them: apples[7] = nil Of course, you can't use general for loops anymore. In the example above, using general for loops will mean that apples[8], apples[9] and apples[10] will be ignored. Then you need to set apples.n = 10 and use "for i=1,apples.n do" instead of &...

Thanks for your efforts mikembly, but i'm not sure if tables are going to work for me. Because I would idealy like to remove the destroyed apples from the table, so the table wont end up being astronomical if run for a long time. But say I have a table of 10 apples and i remove apple 7; then apple 8...

What i need is probably easy, but i'm not that experienced with lua yet and can't seem to figure it out. I want to be able to spawn any number of entities (they're going to be apples), wether each is red or green should be random, and I need to be able to destroy them individually. I've gathered tha...

I've been trying to do something similar in my game. I want to know when a sensor on the bottom of my character is no longer colliding, so I can know when my character shouldn't be able to jump. I have not yet found a good solution for this. This is how i sorted out jumping in my game... function u...

I have a shape that is set to be a sensor, I need to do something when the sensor object is no longer touching/intersecting any other object. Does anyone know how I can achieve this? Thank you.

A simple solution that works for me. Instead of defining every peice of ground in your world, just define a part of the player character which should be treated as the feet. So add a small extra shape to the body at the bottom of the character, and code your collision callback so jumping can only ha...
