I want to display data that is changed every frame (coordinates mostly). I've tried PrintCenterTextAll, it's working but has some bad size limits. PrintHintTextToAll is ear rape. Was unable to get ShowHudText working. So, how do I use ShowHudText and what are other possibilities?

[psychonic]

Hud text is not supported on every game (notably missing on CS:S and DOD:S). You could try a tsay-style message, but I don't know if those can update that fast.

TF2. What's tsay-style message?

[psychonic]

If it's just for tf2, Your best bet is probably to use Hud text. If you're having trouble with it still, paste your code.

By tsay-style, I mean the type of message sm_tsay does. See Sourcemod's basechat.sp for an example.

PHP Code:

SetHudTextParams(0.6, 0.6, 1.0, 128, 128, 128, 128, 0, 0.0, 0.0, 0.0);
for (new i=0;i<MaxClients;i++) {
       ShowHudText(i, 1, "Foo");
       }

Client indices are 1 to MaxClients (inclusive). The script is probably erroring out at client 0 (world). You should also add checks to see if the client exists, or else it'll probably fail as well.

PHP Code:

for (new i = 1; i <= MaxClients; i++) {
    if (IsClientInGame(i)) {
        ShowHudText(i, 1, "foo");
    }
}

It'll edit and reply.

I'd run all of these checks

IsValidEdict()
IsClientInGame() 
IsPlayerAlive()

[bl4nk]

There's no need to check IsValidEdict or IsPlayerAlive. The edict will always be valid for entities 1-MaxClients and you can display hud text to people who aren't alive/spectating with no problems.
