hmm i believe there might be a few file consistency plugins floating around the forums at www.amxmodx.org which will force clients to have the same file as the server

You're going to lose half of your players because so many people use custom models, but here this should do it. Most of this is the work of Zormonstor.rnrn

public plugin_precache() {rn	enforce("models/player/us-inf/us-inf.mdl")rn	enforce("models/player/us-inf/us-para.mdl")rn	enforce("models/player/brit-inf/brit-inf.mdl")rn	enforce("models/player/axis-inf/axis-inf.mdl")rn	enforce("models/player/axis-inf/axis-para.mdl")rn}rnrnrn///////////////////////////////////////////////rn//// FILE ENFORCEMENT /////////////////////////rn///////////////////////////////////////////////rnrnpublic enforce(const file[]) {rn	if(file_exists(file))rn		force_unmodified(force_exactfile, {0,0,0}, {0,0,0}, file)rn	return PLUGIN_CONTINUErn}rnrnpublic inconsistent_file(id, const filename[], reason[64]) {rn	new nick[32], steamid[32], useridrn	rn	get_user_authid(id, steamid, 31)rn	get_user_name(id, nick, 31)rn	userid = get_user_userid(id)rn	rn	new output[128]rn 	format(output, 127, "^"%s<%d><%s>^" inconsistent file ^"%s^"", nick, userid, steamid, filename)rn	rn	// No matter what Im logging the infractionrn	log_amx("%s", output)rnrn	new players[32], numrn	get_players(players, num)rn	rn	for(new i = 0; i < num; i++)rn	{rn		if(get_user_flags(players[i]) & ADMIN_LEVEL_H)rn			client_print(players[i], print_chat, "%s", output)rn	}rn	rn	format(reason, 63, "%s - Custom models prohibited^n", filename)rnrn	return PLUGIN_CONTINUErn}

theres no includes or plugin init in that code

I wrote it under the assumption that he knew how to compile as he'd have to to use it, and thus had some knowledge on the includes and initialisation. If you need help doing that let me know, smiffy.
