Try this, if it doesnt work then u need to set specific model on that model command
PHP Code:
#include <amxmodx>
#include <amxmisc>
public plugin_init()
{
register_plugin("Block Models", "1.0", "$[Y]Y~#Rocks");
register_concmd("model","block_cmd");
}
public block_cmd(id)
{
client_print(id, print_chat,"This Command Is Blocked.")
return PLUGIN_HANDLED;
}
