Gideros Player problem. Missing Box2d

kussakov

I have a problem.

I have the latest Gideros (2018.6.3, also tried with 2018.6.2)

I tried to install Gideros Player for iOS.
First of all - the latest Gideros ships with a very old iOS player GiderosiOSPlayer.zip (from 2016 which does not work for me).
This is not a big deal since we can export "Player" only (from Export Project).
So I exported a player only, compiled in Xcode and installed on an iOS device.
The player starts just fine, but when I try to run something it says:
module 'box2d' not found:
no field package.preload['box2d']
no file './box2d.lua'
no file './box2d/init.lua'
no file './_LuaPlugins_/box2d.lua'
no file './_LuaPlugins_/box2d/init.lua'
no file '/usr/local/share/lua/5.1/box2d.lua'
no file '/usr/local/share/lua/5.1/box2d/init.lua'
no file '/usr/local/lib/lua/5.1/box2d.lua'
no file '/usr/local/lib/lua/5.1/box2d/init.lua'
no file './box2d.so'
no file '/usr/local/lib/lua/5.1/box2d.so'
no file '/usr/local/lib/lua/5.1/loadall.so'

Tried the export on Windows and Mac - same thing - no box2d.

(FYI: I have one project that does not use box2d and it works).

Please help!

------------------------

When I run this in the Gideros player:
for k in pairs(package.preload) do
print(k)
end


I get the following from the built in player:
lsqlite3
box2d
bit
accelerometer
cbump
lpeg
microphone
mime.core
gyroscope
json.safe
steam
lfs
geolocation
theora.core
controller
camera
clipper
socket.core
media
struct
json
liquidfun

And just this on iOS player:
gyroscope
geolocation
accelerometer

Because it’s functionnality is given by liquidfun plugin, which is a more advanced/up to date version of box2d. Removing box2d from core allows to build lighter binaries in case one don’t need physics, and I ensured that all was needed to retain compatibility was to include liquidfun plugin in the user’s project

@kussakov I think you just need to add it as a plugin: it was removed from default player. (if you search the forum there was an explanation I can't recall right now.. )

no need to rewrite code, liquidfun plugin uses the same bindings as box2d

OK. Makes sense. I saw the 2018.6 announcement, but did not realize it has been completely removed, since the windows Gideros player still has it and my projects work without any changes in the Windows Player. Maybe it should be removed from there for consistency?
Also hope it is completely compatible, otherwise I am screwed...
Tested on project by replacing "require "box2d"" with "liquidfun" - works so far ... which is good.

It's 100% compatible, appears faster, and it's more fun!

I've released two games using Box2D, and they work great with Liquidfun rather than Box2D. Try out the particles in Liquidfun, they're really cool!

Here is a video of what can be done in LiquidFun using Gideros...
