Change Player Mugshot for diffent level?

[Graaicko]

So I would like to know if it is possible to change the players face sprites after a certain level. I have two sets of face sprites I created for my character wearing a mask and when the level is completed I would like it to switch to the sprites where he is no longer wearing the mask. How would I do this?

My response would be an entirely custom made mugshot system in ACS / Zscript! A total overkill to do just that, but it'd be possible... for the generic Doom HUD, as you'd need to position it yourself, so any custom HUDs would de-sync pretty easily.

No need for a new system. But i think this could be easily done with zscript statusbar.

The main problem here is that the player's Face property cannot be modified from user code, so a ZScript-based HUD is likely the only way to solve this at the moment. It is possible to leverage the existing GetMugshot method and work with the value is returns: if you need to alter the mugshot, you can use TexMan.GetName and TexMan.CheckForTexture to find a replacement for the original texture returned by GetMugshot and then draw it.

Suppose you have a collection of mugshot graphics that represent the masked player. For this to work, they must follow the same naming convention as the original ones, but with a different 3-letter prefix (e.g. STFST20 -> MTFST20).

Now, in your custom status bar class, you can implement the following method:

Code: Select all

private TextureID MyGetMugshot(int accuracy, int stateflags = MugShot.STANDARD, String default_face = "STF")
{
    let result = GetMugshot(accuracy, stateflags, default_face);

    if (result.IsValid() && IsPlayerMasked())
    {
        // Modify the name
        string texName = TexMan.GetName(result);
        texName = "MTF" .. texName.Mid(3);

        // Find replacement graphic
        result = TexMan.CheckForTexture(texName, TexMan.Type_MiscPatch);
    }

    return result;
}

private bool IsPlayerMasked()
{
    // TODO: Return true if the player is currently masked.
}

The biggest inconvenience here is that GetMugshot is not virtual, so you cannot just replace it and be done with it. It might warrant a feature suggestion, but the proper way to go is being able to modify the player's Face directly, which is not possible at the moment. That's what the suggestion should be about.

Right now, if you want to use the Doom status bar in its unchanged form in your mod, below you will find the complete ZScript code for that.

        if (result.IsValid() && IsPlayerMasked())

            // Modify the name
            string texName = TexMan.GetName(result);

		}

	}
}

You will also have to add the following to your MAPINFO so that the new status bar becomes active:

Code: Select all

gameinfo
{
    StatusBarClass = "MyDoomStatusBar"
}
