here is another trick (what can collide with what) no matter what world (Gideros or Box2D) we are in. here we define some category BITS (that is those objects can collide) - 2^15 = MAX Then, to launch a specific Gideros application, for example, Gideros Studio. After Gideros Player opens, the start and stop icons become enabled. Now select PlayerStart Local Player to start Gideros Player.

My complete set up looks something like this (please note I am using Gideros framework, code is in Lua): - here we store all possible objects name - NO LIMIT At the first part of this tutorial, we just want to run our code in Gideos Player and print Hello Ball to the console. From the game engine's point of view, a physics engine is just a system for procedural animation. Programmers can use it in their games to make objects move in realistic ways and make the game world more interactive. For example: if g_currentlevel = 1 thenĪnimspeed=14, movespeed=8*0.6, jumpspeed=8*0.5, maxnumjump=2,īIT=G_BITENEMY, COLBIT=nmecollisions, NAME=G_ENEMY, Box2D is a 2D rigid body simulation library for games. You will define those abilities upon creating them. You have many enemies, you put them in the ENEMY category.Īn enemy is an enemy regardless of its abilities like size, speed. Then I found a solution: you don't need to use all 16 bits, you need to categorize your objects.įor example, you have some grounds and solid platforms, you put them in the SOLID category. When I first used box2d I quickly reached the 16 bits limit :-)
