 |
|
is there any way to stop the arrow keys from making you walk? i made a script that makes you look in the direction you press and then if you hold it you walk in that direction. but it isnt working because the arrow keys are still making you move so its getting you off the grid and ignoring walls and just generally bugging up

At the beginning of the script, use suspend player and when the script is finished, use resume player |

The secret is that scripts happen before anything else. Unfortunately this also means that you won't find out about what happened (NPCs and heroes starting a new move, textbox appearing, etc) until the player has already seen it.

Okay, this got me curious, so tried to do it myself, and I came up with these two scripts:
| Code: |
include, plotscr.hsd
include, scancode.hsi
define constant(0, look timer)
plotscript, on key, begin
show value(seconds of play)
variable(looking)
looking := false
if (keyval(key:Z) >> 0) then(
# Look without walking if Z is held down
stop timer(look timer)
if(keyval(key:UP) >> 1) then(set hero direction(me, up), looking := true)
if(keyval(key:RIGHT) >> 1) then(set hero direction(me, right), looking := true)
if(keyval(key:DOWN) >> 1) then(set hero direction(me, down), looking := true)
if(keyval(key:LEFT) >> 1) then(set hero direction(me, left), looking := true)
if(looking) then(
suspend player
)
set timer(look timer, 1, 1, @finish look)
)
end
script, finish look, begin
resume player
end
|
It would indeed be nice if there was an easy way to cancel a keypress. it would make this sort of script much simpler.
We already have a clearkey() function in allmodex.bas. I suppose if we exposed that to plotscripting, then the script could be written like this:
| Code: |
include, plotscr.hsd
include, scancode.hsi
plotscript, on key, begin
if (keyval(key:Z) >> 0) then(
# Look without walking if Z is held down
if(keyval(key:UP) >> 1) then(set hero direction(me, up), cancel key(key:UP))
if(keyval(key:RIGHT) >> 1) then(set hero direction(me, right), cancel key(key:RIGHT))
if(keyval(key:DOWN) >> 1) then(set hero direction(me, down), cancel key(key:DOWN))
if(keyval(key:LEFT) >> 1) then(set hero direction(me, left), cancel key(key:LEFT))
)
end
|
So much simpler! |

i got it to work by doing
| Code: |
while (key is pressed(57))
do (suspend player
while (key is pressed(57))
do (
if (key is pressed (72))
then (set hero direction(0,up))
if (key is pressed (75))
then (set hero direction(0,left))
if (key is pressed (77))
then (set hero direction(0,right))
if (key is pressed (80))
then (set hero direction(0,down))
wait (1))
wait (1)
resume player
)

basically if you are holding space, it sets your direction instead of walking. I had to use 2 seperate While/Do statements so that resume player didnt happen while it was repeating. But this seems to work. My only concern is that it doesnt allow any of the other on keypress scripts to run while you are holding space

The key handling code has been rewritten a couple times in the last year or two, and I can no longer remember whether clearkey has been fixed, but I don't fully trust it and avoid using it. Anyway, I think that this is a feature we should have, but maybe we should provide it in a different way: by letting people suspend and resume keys? Hmm, maybe we'd want clearkey anyway for convenience.
I can't see a reason why it wouldn't work with one of the while loops deleted.
What do you mean by "the other on keypress scripts"? Are they bits of code inside the same keypress handlig scripts? Do they contain their own weights? Is "permit double-triggering of scripts" enabled? It would be possible to let them continue to work while space is being held down.

I did a test of this. Actually I had to call it "suppress key" to avoid collision with the existing "clear key" constant for the "wait for key" command.
It did not work properly at all. I am guessing you are correct that clearkey() in allmodex.bas has bitrotted. it is only actually used in a very small number of places. |
