I've been trying to code enemies to load into the map with a certain idle state shows all of their angles (whether they see the player or not). Now, I got that to work easily enough, but I also wanted them to pursue the player ONLY if he was in a certain field of vision, so I figured what I could do was get the angle difference between the player and the enemy (i.e, what angle the enemy would have to be at to be facing the player), then add and subtract a number from it, and only have the enemy go into it's seeking AI if it's angle fell between the two numbers that were produced.

ifai AIT1IDLE // if the bad guy is in his idle state
{ ifcansee {
getplayer[THISACTOR].posx PERPLAYER1 
getplayer[THISACTOR].posy PERPLAYER2
getactor[THISACTOR].x TEMP1
getactor[THISACTOR].y TEMP2
subvarvar TEMP1 PERPLAYER1
subvarvar TEMP2 PERPLAYER2
getangle TEMP3 TEMP1 TEMP2 // get the angle he'd have to be at to be facing the player
ifvarl TEMP3 0 { mulvar TEMP3 -1 } // and if that angle happens to be less than zero, multiply it by -1
setvarvar TEMP6 TEMP3
setvarvar TEMP7 TEMP3 // store that value in two separate vars for later use


getactor[THISACTOR].ang TEMP5 // get the actor's actual angle

subvar TEMP6 200 // subtract 200 from one of the stored values
addvar TEMP7 200 // and add 200 to another, so this should create an array of values between TEMP7 and TEMP6 where the enemy can see the player

ifvarvarl TEMP5 TEMP7  { ifvarvarg TEMP5 TEMP6 { ai AIT1WALK } } // if the bad guy's angle is greater than the minimum needed angle, but less than the maximum, have him seek the player

This code does, in some small capacity work. Only problem is, it isn't working from the angle I 'need' it to be working from. The bad guy only goes into his seeking AI if I'm behind ( and usually kind of off to the side of) him. If I'm in front of him, he just stands there. The only thing I thought could fix this problem was adding 1024 to the needed angles, thinking that'd flip the values around or something, but he didn't do anything at all when I did that. Can anyone tell me what I'm screwing up?

EDIT: Nevermind, I think I just got it to work. I don't know if the math was suppose to be like this, but I flipped it around to where the enemy's angle subtracts from the player's angle, and it's working like a charm now.

I have working code for this somewhere. It goes like this:

1) Calculate the angle that would make the actor face the player (let's call this ANGLE1)

2) Use getincangle to calculate the difference between the actor's current angle and ANGLE1. The difference, which is the return var of the getincangle command, we will call DIFF.

3) If the absolute value of DIFF is less than 512 (or whatever number you deem appropriate) then the player is in the actor's cone of vision.

Hmmm. I gave it a whirl and didn't have any luck, I may have misinterpreted something, though I've changed everything that might have caused it not to work, and the guy still switches into his seeking ai.

ifvarl TEMP3 0 { mulvar TEMP3 -1 }
getactor[THISACTOR].ang TEMP5 // get his current angle
getincangle TEMP7 TEMP3 TEMP5 // get the difference between the two. When I first tried this, I had TEMP3 and TEMP5 swapped around, and he'd switch into his seeking ai as soon as I entered
// the room. With the variables like this, he doesn't do it immediately but he winds up doing it if I get to close, even though I haven't changed angles.

ifvarl TEMP7 512 { ai AIT1WALK break } // changing 512 to any other value doesn't seem to do anything


} }

I probably just royally screwed something up, but I've made all the changes I can think of.

[Danukem]

Do not mulvar TEMP3 -1, because that will mess up the result of getincangle

Instead, use ifvarl TEMP7 0 mulvar TEMP7 -1 after the getincangle

If you look at my previous post, you'll notice that I said to use the absolute value of the result of getincangle, not to change something to an absolute value before getincangle

I'm assuming you have your variables in the correct order for getangle etc.

Yeah, that must've been what I did wrong, because I moved that line below the getincangle command and it works. So I've got two functional methods of doing this now, but I think I'll probably end up using yours because it's a bit less code-intensive and it looks like it can be manipulated to work with player distances a bit more easily as well. Thanks, DT.

Hello!

The other day I decided to make it so the palfrom "tint" that comes on screen when the player takes damage, to be controlled through gamevars and the .pals on the player strcture.
However, I can't see how to set the "tensity" using .pals and didn't see anything else that could control this. Without the tensity, even a colour of 64 is very faded.

So, how can I control the "tensity" of tints set through .pals.

Do you mean intensity? If so, then it's controlled by the pals_time member of the player struct. It's not stated in the description, but the greater the time left, the greater the intensity.

[Chip]

Yeah, I did mean intensity.

Thanks!

How do I use the readarrayfromfile and writearraytofile commands? I tried the obvious (putting the array name after the command) but it just tells me it's a keyword and throws up an error.

readarrayfromfile <arrayname> <quote#>


The name of the file that the array is stored in will be the quote

writearraytofile works the same way. I can add that to the wiki later, if no one else does.

[Jblade]

Cool! just tested it and it works thanks!

[Jan Satcitananda]

Lol I've got it. If we load an ART file into an array, it might be possible to access some textures directly via the script (for read only, of course).

EDIT
Added some shit to the Wiki (finally got to register, lol).

Could someone help me to code a little thing?
I wanted to make a sprite, that's invisible.
When you shoot it, it disappears and a looping sound is playing, so that the sound never goes away.

Is this possible, with that looping sound thingy, because it never works for me

Thanks in advance guys!

Making a sound effect loop is easy. http://wiki.eduke32....iki/Definesound You just set the sound effect's "type" to 3, so it can be used for a music/sfx sprite, and it'll loop (1 is the important part of the bit-field, as it's what actually makes the sound loop). I'd be able to throw together some code so you could see how it'd be done, but I really don't get what you mean in the rest of the post. I mean, if the sprite's invisible in the first place, you wouldn't have to make it 'turn' invisible when it's shot...

No, I know. What I meant is that the sprite has to disappear eventhough it's invisible. I think it's done with the "killit" command, so when you shoot it again nothing happens.
I just don't know what to put first or to start with.
I got this, and trying to figure out what to do and such:

define WINDACTOR 19

useractor notenemy WINDACTOR
cstat 32768
ifpdistl 864
 ifcansee
  ifp palive
      ifhitweapon
      {
       soundonce WIND
      }
enda

But this doesn't does anything.

There could be several different things wrong with that code that's causing it not to work. If its cstat is set at 32768 it will, indeed, be invisible, but it won't do anything when hit by a weapon because it doesn't have the proper bits to make it "hittable" (or however you'd phrase that). You'll need to add 256 to the cstat (see the cstat page on the wiki to get an idea of how all the bits work). Also, can't really confirm it, but that ifpdistl line could be throwing things out of whack too. A distance check probably isn't necessary if you just want it to execute some kind of code if it gets hit, here's some rough code that'll mostly achieve the effect you're going for...

Quote

define THIS_VAGUELY_DESCRIBED_THING_THAT_IS_INVISIBLE 3327

useractor notenemy THIS_VAGUELY_DESCRIBED_THING_THAT_IS_INVISIBLE 0
cstat 33024
ifhitweapon { sound BAR_MUSIC } enda

That'll make the actor invisible and be receptive to hits, but it won't be blocked so the player can still walk through it. There's no real need to change the actor after its been hit, because it'll just keep playing the same sound, but it won't start it over again. You definitely won't want to use killit (i.e, delete it from the map) because that'll stop playing the sound altogether. I don't know how your wind ambience sound is defined, but for the bar music sound, I had to change its definesound from this

 definesound BAR_MUSIC		   barmusic.voc	   0   0 254   2   0

to this

 definesound BAR_MUSIC		   barmusic.voc	   0   0 254   1  0

The sound won't loop if you don't change that one little bit.

[Simon_Croes]

Great! That worked well!
Only one little thing, could the hitscan of the invisible sprite be removed?
Because eventhough blocking and hitscan is turned of in mapster32, it still got this hitscan effect on it.

Thank you so much EmericaSkater!

Just change its cstat back to 32768 after it plays the sound. That oughta do it.

[Simon_Croes]

It worked great
Thanks again EmericaSkater.

BTW, is it possible to remove duke from cracking his knuckles? Like when the game starts and when he waits too long?
I found a command in the Eduke32 Wiki like "knuckle_incs"

Can I remove duke from doing that cracking with this command?

[Danukem]

That's not a command, it's a member of the player struct, and you can use it to prevent knuckle cracking by constantly setting it to zero.

setplayer[THISACTOR].crack_time -1

In the APLAYER code.

Thanks Commander, and also for PM'ing.

[The Commander]

I woudnt have PM'ed it if I knew this was the scripting thread.
I thought it was the DukePlus thread.... (dont ask, I am tired and drunk)

[The Commander]

Is there anyway to force the main menu background tile to not be dark.
I have tried to mess around with the shade and orientation in EVENT_DISPLAYMENU but I can only achieve making the tile darker or black.

I am not tempted to rewrite the whole menu in EVENT_DISPLAYMENUREST.

EDIT: I tried to photoshop the tile I am using to be brighter, but it does not look like the background I see when I look at the eduke32 credits section.

That doesnt seem to stop Duke from cracking his knuckles at the start of a level, though. Hmm.

You could always delete the sound and tiles so you can't see it anymore.

pretty sure knuckle_incs should be 0

That's what I told him.

[CruX]

Crack_time is just a counter that knuckle_incs operates on, if I'm right. I think setting it to negative one would keep it from happening, but it still occurs at the beginning of the level if you don't actually alter knuckle_incs.
