 Posted: Sat Aug 12, 2006 9:54 pm Post subject: Problem with running script when key is pressed |
 |
|
This script has a problem, but I don't know what it is. When the script is run, the character ends up getting stuck in the tile it advances to and it keeps moving (as in the animation), but the character just sits there and you can't open a menu. Is something wrong with it? How would I make a script if this one isn't correct, so that a character will run when you hold down a key?
| Code: |
script,Run,begin
if (key is pressed(key:Z))
then,begin
set hero speed(0,5)
end
else,begin
set hero speed(0,4)
end
end |

Apparently the guys who work on the engine decided to change 'key is pressed' to 'keyval' without updating the dictionary.
Keyval is the exact same thing as key is pressed. |

You should not change speed while the hero is moving. That causes it to become misaligned with the tiles, and gets you stuck. Try wrapping the code in an if block that checks to make sure the hero is not currently walking before changing the speed.
| Code: |
script,Run,begin
if(hero is walking(0))
else, begin
if (key is pressed(key:Z))
then,begin
set hero speed(0,5)
end
else,begin
set hero speed(0,4)
end
end
end

As for the key is pressed vs keyval, yes there is a change in the behaviour of key is pressed, but not one that could cause this problem
The new behavior of key is pressed is to return true or false depending on whether or not the key is being pressed. The documentation didn't change, because the old implementation of key is pressed did NOT really do exactly what the documentation said.
The old key is pressed (and the new keyval) does the following:
0 if not pressed
greater than 0 if pressed
greater than 1 on key-down and key-repeat
If you wanted to use keyval here, and take advantage of its original keypress detection, you would write:
| Code: |
script,Run,begin
if(hero is walking(0))
else, begin
if (keyval(key:Z)>>1)
then,begin
set hero speed(0,5)
end
else,begin
set hero speed(0,4)
end
end
end

Awesome, now the script runs without much of an issue! Now I also understand better the "hero is walking" plotscripts command and such better as well. Thanks!
