Displaying and Hiding Images That Take Up the HUD

[ReedtheStrange]

I already know how to use HudMessage, SetFont, SetHudSize and SetPlayerProperty to display an image and disallow the player from moving, but what I want to know how to do is allow the player to stop viewing the image at anytime, rather than having a set time. I'm almost there, but I'm just stumped on the part about allowing the player to leave right after they're done reading.

You'd need to set up a script to detect the player hitting a button. Here's one from Reelism for you to use as a base.

To test it, run script 994 (puke 994 in console), then press the Use key to end the map.

Code: Select all • Expand view

script 994 (void) // ending use button detection.
{
int buttons = GetPlayerInput(-1, INPUT_BUTTONS);

if (buttons == BT_USE)
{
    Exit_Normal(0);
}
delay(1);
Restart;
}

It does work. I'm thinking maybe having use the backpedal button be the exit button because you need the use button in order to read the screen in the game. But I can't find these commands on zdoom wiki.

And the thing that kind of sucks too is that ACS_Terminate isn't doing anything.

I guess the best question is what ACS function hides an on-screen image.

There technically isn't a function made for that purpose, however, what you can do is the following:

Code: Select all • Expand view

HudMessage(s:""; 0, ?, 0, 0, 0, 0);

Where ? is the id of the message. Make sure it's the same as the one of the message/image you're trying to hide.

It doesn't appear to be working. I also tried it with another image instead of no images and the image printed over the first image.

[Blue Shadow]

Hmm, that's weird. It shouldn't display the new message over the old one. It should replace it.

At this point, I think seeing the code might be helpful.

Fixed it. As I suspected, my ADD was the culprit. Everything is working now!
