[FFS2309]

English:

 

Hey,

I'm new in modding and I want to write an Minecraft Mod which adds an Logitech G19(s) applet but I haven't figured out how to get the players life or foodlevel

if the Client connects to a server or one of those are changing.

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

German:

Hey,

Ich bin recht neu im modden und habe vor ein applet für die Logitech G19(s) zu machen doch ich kriege es einfach nicht hin das Leben / den Hunger Status des Spielers zu bekommen wenn er auf einen Server verbindet oder sich das Leben bzw. der Hunger Status ändert.

 

Mfg FFS2309

It is an unmodded bukkit server maybe this is the problem ?

Or is there any Event which I can user for connecting, but then i also need one for the change of the value of live and foodlevel

 

Mfg FFS2309

 

//EDIT

At line 61 I'm having the code p.getHealth();

if I remove this it is throwing the same exception but with the line from p.getFoodStats().getFoodLevel();

[FFS2309]

1. Like sayed in the first post I'm writing a mod which gets info like Health and displays on a Logitech G19s

2. How do I use a TickHandler ? I've searched in the jds, google(in the most time useless cause you only find stuff like how to install forge ...) and in this Forum but I don't find any way for 1.7.2

1. I need like nothing from Forge , only Playerinfo the rest is to get a Graphics object from the Keyboard where I draw everything and the code for my Classes:

The Proxy classes don't contain any code,  only a registerRenderers() method of type void which also contains nothing

 

2. I think I should use that as normal Event or is there something special ?

[FFS2309]

Thanks, I will try but isn't it very performance intensive to check every time ? (I don't care it has to work fine on my pc but if I would publish it in the far future is that something I would care about)

[FFS2309]

Thanks that is working just fine but only with TickType.PLAYER else the client crashes
