How to retrieve current FOV in ACS?

[Nash]

Is there a way to accurately retrieve the player's current FOV in ACS?

GetCVar("fov") doesn't work because, understandably, fov isn't a cvar.

Well, I just realized this isn't possible... hacked something together real quick which seems to work...

Code: Select all • Expand view


        // [Nash] get current FOV
        case ACSF_GetPlayerFOV:
            actor = SingleActorFromTID(args[0], activator);
            if (actor != NULL)
            {
                if (actor->player != NULL)
                {
                    return (int)actor->player->FOV;
                }
            }
            else return 0;
 

Seems to work. Any hidden problems I need to be aware of?

Why not make it retrievable like ACS actor properties instead of a new function just for that?

Also, I believe non-players have a FOV of 180 unless they have the LOOKALLAROUND flag in which case it's 360. (I can't check at the moment.)

Monster field ov view can also be changed in A_Look, so the correctness is not guaranteed.

Well I'm apparently too dumb to find the name of the field that stores an actor's FOV... :/

Spoiler:

Help :B

It's not stored, that's why. It's either contained in the A_Look call, 180°, or 360°.

Well then that's too much work for what I intend to use this for anyway. I was only interested in the player's FOV so that 3-d -> 2-d HUD elements scale properly with dynamic FOV...
