How to make a kinematic object act like a dynamic object?

I would say that it depends on what you wish to do. Do you wish to do a platformer with typical platformer physics (gravity, double jump, wall jump etc), a Thrust kinda game (gravity, rotation, thrust and drag), a top-down racing game or something else? Sure, you could implement a full physics system using kinematic objects, but it will become a fairly complex system.

Now, I’ve wrapped up most of the logic required for a platformer game into a platformer.lua module:

github.com

britzl/ludobits/blob/master/ludobits/m/platformer.lua

--- Wrapper for the physics and behaviour involved in creating a platformer
-- game

local M = {}

local CONTACT_POINT_RESPONSE = hash("contact_point_response")

--- Create a platformer game logic wrapper. This will provide all the functionality
-- to control a game object in a platformer game. The functions will operate on
-- the game object attached to the script calling the functions.
-- @param collision_hashes Table with hashes for the collision groups that
-- prevents movement and where collisions should be resolved
function M.create(collision_hashes)
	collision_hashes = collision_hashes or {}
	for _,h in ipairs(collision_hashes) do
		collision_hashes[h] = true
	end

	local instance = {
		velocity = vmath.vector3(),

If you want a Thrust type of game I think you should take a look at the code for Rocket Run by Ben James.

And if you’re interested in a racing game maybe look at Pastel Riders by Mathias Westerdahl
