I am new to modding but I am making a custom sword that strikes entity's with lightning when hit.

I am able to dissable the function with the L key but I want to show a chat message when activated.

Please help

 

or player.sendChatMessage(String) if you just want to send a string.

(works only by EntityPlayerSP)

can you give me examplecode

PS: I am using forge 1.7.10

send chat message doesn't work the error is :The method sendChatMessage(String) is undefined for the type EntityPlayerSP.

can you please give me an examplecode of a method thats sends a chat message

player.addChatMessage(new ChatComponentText("Learn Java."));

how do you make the player object

To get the player object, you first need to learn Java, and then suddenly realise it's magic, and you get it by using the parameters of the method.
