 |
|
im trying to figure out how to make my character levitate when i press a button but it never works. i looked at the plot dictionary but that didnt help.
HERES THE SCRIPT:
script, JUMP, begin
wait for key (37)
key is pressed (37)
set hero z (0,6)
wait for hero
set hero Z (0,0)
end

gRAPHICS: Does he have teh shadow? Make that a sepparate Npc that pops up below him.
Plotscripting: (I am a know nothing) That looks like it should work. The wait for key command is necessary? Are the Zs supposed to be not case sensitive?

hmmmm.....let me take a shot at this.
| Code: | Script,Jump,begin
if(key is pressed (37) == true),then
(
set hero Z (0,6)
)
else
(
set hero Z (0,0)
) |
that's very basic, so you'll have to add your own stuff in there. That'll make him levitate while the key is pressed, or at least it should. I have yet to test it. Let me know if it works

you do know that "set hero z" is an instant command... like "set hero position" it sets the "z" position of the hero instantly.
so your code:
| Code: | script, JUMP, begin
wait for key (37)
key is pressed (37)
set hero z (0,6)
wait for hero
set hero Z (0,0)
end |
won't work, because it instantly sets hero "z" to 6 then instantly sets it back to 0, os the final result will be to keep it at 0, as if it hasn't done anything.
what you may want is something like this:
| Code: | script, JUMP, begin
if(key is pressed (37)) then(
set hero z(0,1),wait(1)
set hero z(0,2),wait(1)
set hero z(0,3),wait(1)
set hero z(0,4),wait(1)
set hero z(0,5),wait(1)
set hero z(0,6), wait(2)
set hero z(0,6),wait(1)
set hero z(0,5),wait(1)
set hero z(0,4),wait(1)
set hero z(0,3),wait(1)
set hero z(0,2),wait(1)
set hero z(0,1),wait(1)
set hero z(0,0)
)
end |
this will give the hero a "jump" look to it. it would look a lot more clean with a loop instead of all that, but let's just use the basics for now.
You may also want to make the hero to jump in the direction it is facing.

Havent tested this yet but it seems okay. To define:
define script (autonumber, jump, 1, 0)
and to use:
jump (me) # where me is the hero's number/name
| Code: | script, jump, hero, begin
variable (counter)
counter :=0
if (key is pressed (37))
then (
if (counter <= 6)
then (
set hero z (hero, counter)
increment (counter)
wait (1)
)
else (
if (counter >= 0)
then (
set hero z (hero, counter)
decrement (counter)
wait (1)
)
else (end)
)
end |
Yaay, a function!

Do you have a keypress script? The way I see it... I don't think the script will work at all without a keypress script. something like this...
| Quote: |
global variable(999, button)
script,keypress,key,begin
write global(999,key) #or "button:=key". I just like write global a lot.
end
|
Then you replace "button" every time you need to check which key is pressed on the map. This probably isn't the best way but you have to set the "run script on keypress" thing in the map data menu to something.

*smacks forehead at the general nonsensualness of the replys*
First, about the scan codes, I recomend including scancode.hsi at the put of your files, just like you would plotscr.hsd. That way you can use write
if (key is pressed (key:l))
without having to look up the number each time.
Secondly, you CAN'T use scancodes with wait for key! It only accepts constants like 'anykey', 'cancel key' and 'upkey'. See the dictionary definition. That's why your script doesn't work.
Finally, for a jump script:
| Code: | script, jump, hero, begin
variable (counter)
counter :=0
if (key is pressed (37))
then (
if (counter <= 6)
then (
set hero z (hero, counter)
increment (counter)
wait (1)
)
else (
if (counter >= 0)
then (
set hero z (hero, counter)
decrement (counter)
wait (1)
)
else (end)
)
end |
why increment ordecrement the counter if its a local and is always at zero? There is no way to check hero z, you have to store it in a global if you want to use it across scripts. Don't forget whether you've already set it at somethign under the general map options.
Now, if you want a jump script with a physical correct smooth curve:
| Code: |
script, jump, begin
variable (current height, ctr)
while (current map == 5) do ( #change this to the map number or other criteria
if (key is pressed(key:j)) then(
current height := 0 #adjust this to the height offset under map options
for (ctr, 3, -3, -1) do(
increment(current height, ctr)
set hero z(me, current height)
wait(1)
)
)
)
|
This code will also allow the hero to jump forwards or backward, as player is not suspended.
Feel free to change the 3, -3 to change the height of the jump. But there must be opposite in value, or the hero will end up in the sky or floor.
Not its for hero 0 only, but its not hard to change.
Misc:
Leroy_leo: you don't need chenge the direction of the hero, hero z is just the amount of pixels above the tile the hero is drawn. But you may want to change the heros palette to draw him in mid jump.
Sephy: That would only be needed if you had more than one thing that needed to check the key presses every second, or you could run thenm all into one loop. |

PS: That script would only jump the hero up 6 pixels. You may want to change 3,-3 to 4,-4, 5,-5, or 6,-6 for a 10, 15 or 21 pixel high jump.
Hmm... I think I'll add that script to my library... |

If you want, you could also have the script so it had the hero levitate while the button is held, as problems can sometimes arise from toggle keys (note: this is edited from James' old optimization of my run script:
| Code: | if,begin
key is pressed (37) #change this to choose your own key
end
then,begin
if (hero is walking (me)==false)
then,begin
# levivation stuff
end
end
else,begin
if (hero is walking (me)==false)
then,begin
# non-levivitation stuff
end
end
end |

that'll work... until you run into an NPC triggering another script...
oh well, i doubt it'll be an issue.

I agree with mad cacti
for the following reasons
1. For command goes from automatically increases the variable.
2. out of all the scripts I have seen in this post, this one seems less buggy.
3. and finally, levitate means you stay in the sky, not jump(sorry for any inconvenience.

| Well, Flamer, it goes in the "on keypress" map script. I guess I forgot to mention that... |
