Players don't take damage by knife when this plugin is on. Why?

return Plugin_Handled;

Damage is blocked.

You are looking for plugin changed :/

[berni]

Maybe try to explain what exactly you are expecting from the code lines, and what exactly doesn't work.
eg.: Why should TeleportEntity deal damage ?

[blodia]

looks like hes trying to create knockback

berni, you already fixed the plugin. Thanks for your help!
