Vecx and Vecy
 

Someone mind explaining these two things too me in plain english? :) I know that vec stands for Vector, and I think vectors = speed+direction, but thats where my knowlege ends on this subject ;P

posted a while back.

NPC Code:

---

dir      vecx          vecy         

0         0              -1             

1        -1               0              

2         0               1              

3         1               0              

---

I'm no expert at this, but I would think that if the player was facing down:


vecx(playerdir) //<-- that would equal the tile the player was standing on. (numeral direction for down: 2)

Numeral Directions:
0 Up
1 Left
2 Down
3 Right


Hope it helps.

Err sort of, I still dont quite understand it, thanks though.

What don't you understand about it?

I didn't really understand it at first either.. And it's kinda hard to explain.. Let's see...

*Steals Tarankusu's list*

NPC Code:

---

dir      vecx          vecy         

0         0              -1             

1        -1               0              

2         0               1              

3         1               0

*explains list ferther*
vecx(playerdir) // the best usage for it.
vecx={0,-1,0,1} // like if playerdir {0,1,2,3}
vecy={-1,0,1,0} // like if playerdir {0,1,2,3}
if playerdir = 0, the VECY would = -1
if playerdir = 1, the VECX would = -1
if playerdir = 2, the VECY would = 1
if playerdir = 3, the VECX would = 1

playery=playery+vecy(playerdir)
if he was faceing up, the playerdir would = 0, so it would add -1 to his playery, AKA playery-=1 //in other words.. move him up


playerx=playerx+vecx(playerdir)
if he was facing left, the playerdir would = 1, so it would add -1 to his playerx, AKA playerx-=1 //in other words.. move him left

and so on and so forth... >;/ get it?

So vecx and vecy are for moving the player?

not always.
you can also use them for detecting tiles infront of the players dir.
EXAMPLE:

NPC Code:

---

hitobjects 2,playerx+1.5+vecx(playerdir)*2,playery+2+vecy(pla  yerdir)*2;

---

No, but MOST SCRIPTERS when there new.. they use it for movement...

NPC Code:

---

if (playerenters || timeout) {

moveplayer();

timeout=0.05;

}

function moveplayer() {

for (i=0;i<4;i++) {

if (keydown(i)) {

playerdir=i;

playerx=playerx+vecx(i);

playery=playery+vecy(i);

}

}

---

Yes, that is the kind of thing I want to know, for using with a triggeraction, to detect a player in front of you. Can you explain why the playerx has the +1.5+vecx(playerdir)*2 and the playery has +2+vecy(playerdir)*2 , please?

ask screen_name.

I'm not sure about the playery+2 / playerx+1.5 myself. I tried taking it out, but it didn't work. It doesn't move the player or anything though.

Hmmm... Is there like a guide or something, in plain english for scripting @_@;?

// Delete's post...

I posted a explination.. but explaining.. didn't make it sound right... hehe, i kinda confused myself >;O.. good idea < ask screen_name...

Is for hitting stuff in front of the player... use your imagination

Hmm alright, thanks for your help.

By the way, I was playing around with triggeraction and I can't get it to work,

NPC Code:

---

if (created) {

  showcharacter;

}

if (playerchats&&strequals(#c,Test)) {

  triggeraction x,y,test,;

}

if (actiontest) {

  setcharprop #c,Test_kekeke;

}

---

Should that work, or am I just really dumb?

What's the need for that?

Testing triggeraction ;P

well, you need a //#CLIENTSIDE
and the actiontest goes above the clientsided part.

I was testing offline ;O does that still matter?

i don't think triggering actions works offline...

You use the (actiontest) or whatever in a different NPC usually...If its the same NPC you do a function

Also if it is a separate NPC and the separate one has an image, the triggeraction must be on the image. kind of like opening an NPC, your mouse has to be on its image or that blank NPC outline

It does.

How do u work the mouse thingy anyway?
if (mousex==playerx) {
or something?

open newfeatures2001.txt (or 2002 i forget which one) in notepad, press Ctrl+f and search for the word "mouse" and you should find how to use all of the new mouse, that's how I found out :)

I've never gotten serverside actions to be triggered offline...


And for the mousex questionaire,
I'm not too sure either.

I've tried it all different ways. :(

...read this....it was in new features...
- New script command: triggeraction targetx,targety,action,params;
This is one of the commands that give you like 50% more scripting
power than before. It is like a combination of hitobjects and
callnpc, but better. With 'triggeraction' you invoke an event
to the object on positon (targetx,targety). If the object is
an npc, then the npc script is called with the flag
'action<action>' set, when the object is a player then the
weapon scripts of the that player are called with the
'action<action>' flag set.
'params' can be one or more parameters, divided by commas;
the called script can read the paramters by accessing the
message code #p(paramindex).
Because this is hard to explain with words, here some
little examples:

- trigger player weapons
You can easily do a weapon which freezes the other
player:

if (playertouchsme) toweapons Freezing-Weapon;
if (weaponfired) {
triggeraction playerx+1.5+vecx(playerdir)*2,
playery+2+vecy(playerdir)*2,freeze,;
}
if (actionfreeze) {
freezeplayer 3;
setplayerprop #c,FREEZED;
}

Both players must have this weapon for making it
working. Then use it on the other player, and he will
be freezed, because a 'freeze' action is sent to him
and his weapon script, called with flag 'actionfreeze',
will freeze him. You can also move the if (actionfreeze) ...
into an system npc so the weapon can be used on all
players.
Other nice things you could do with triggering actions
on players: a stealing weapon which lets the other player
loose gralats (if (actionsteal) lay2 greenrupee,... );
complex attacking weapons that use your own hitpoint
system instead of the default hearts thing

- trigger npcs

Until now npcs can only react to 'playertouchsme' and
'washit', other things are very hard to do (e.g. the
mining on Graal2001 was made by checking periodically
what animation the player has and before which stone the
player stands). You could do callnpc, but this works only
client-side and you needed to pass parameters with
flags.
Using 'triggeraction' you can make those things much easier.
The mining axe could have the script
if (weaponfired) {
setani jaxe,hammergold0.png;
triggeraction playerx+1.5+vecx(playerdir)*2,
playery+2+vecy(playerdir)*2,mining,#v(axepower);
}
If you now use the weapon on a stone, the stone npc could
check this so:
if (actionmining) {
axepower = strtofloat(#p(0));
this.power -= axepower;
if (this.power<=0) {
setstring uncraftedgold,#v(strtofloat(#s(uncraftedgold))+1);
hide;
}
}
With this thing you can also easily do switches which are
activated with the hammer, or torch lamps which are turned on
by using a torch on it.

I DID read that, and to me there is nothing wrong with what i coded.

x+1.5
y+1.5

I find triggeraction woorks better when in the middle of the npc/player.

I doubt this is possible, but can you use a call for a function via CLIENTSIDE and have the function DEFINED serverside?

probaby not

Figured as much. Never tried it, lolz.
