Having some problems moving the camera with a script tile. I'm setting unknown to 3 and my script doesn't crash. It simply doesn't move the camera. Even using a waitmovement 0x7F after my applymovement call.

Are you able to post your script so other members can analyse it and find out what's wrong?

Make sure that you're including the commands 'special 0x113' and 'special 0x114' before and after moving the camera.

Special 0x113 and 0x114 were the problem, I hadn't heard about them. Thanks :)

Now am I able to move the camera with the movesprite or movesprite2 cmds? I have a script where this would be much easier than adjusting the camera based on players initial location with an applymovement cmd.

try with the npc id 0xFE (or 0xFF? i can't remember)

 

[pikachux2]

The camera is 0x7F, but as far as I can tell I'm not able to move it with any movesprite cmd. Also having a problem were the sprite whose ID initiates my script keeps turning to face against the player each time I applymovement 0xFF. This is bizarre to me because I'm not even using a faceplayer cmd, or msgbox 0x6 (which I think deals with some kind of faceplayer call, if I'm correct). Even more bizarre because the player moves earlier in the script and doesn't trigger the NPC to move.

Now am I able to move the camera with the movesprite or movesprite2 cmds? I have a script where this would be much easier than adjusting the camera based on players initial location with an applymovement cmd.

There's really only one instant move camera command and its extremely buggy. It will move every OW (including the player) rather than just the camera, resets all OWs original positions after a trainerbattle and if you don't move the camera back to its original position after using it, will mess with the movement permissions of the map. It should only really be used in the context of the video in the thread (looking at something far away) and isn't suited for your purpose at all.

The camera is 0x7F, but as far as I can tell I'm not able to move it with any movesprite cmd. Also having a problem were the sprite whose ID initiates my script keeps turning to face against the player each time I applymovement 0xFF. This is bizarre to me because I'm not even using a faceplayer cmd, or msgbox 0x6 (which I think deals with some kind of faceplayer call, if I'm correct). Even more bizarre because the player moves earlier in the script and doesn't trigger the NPC to move.

I'm not 100% sure why the OW is acting like that based of your script, but make sure that it isn't sharing its 'Person Event Number' with any other OW. If that isn't the case, you could try writing an extra applymovement command each time the player changes their facing direction that changes the troublesome OW's facing direction to the correct one.

Also, you're using setflag 0x113/ 0x114 instead of the special command in your script. Finally, its msgbox 0x2 that has lock/ faceplayer automatically built-in. Here's what it says in the first post of this thread:

Msgbox Numbers
​

Here are the many different types, taken directly from The ROM Hacking Newsletter, also located in the ROM Hacking section.
This week's tip comes from HackMew. This time, it's all about msgboxes. Below is a description, script example and in-game shot of the different msgbox types.

0x2

Spoiler:

Description:
This is the msgbox used for normal people. Using this type means that you don't need to use the lock, faceplayer or release commands.

Script:
#dynamic 0x800000

#org @start
msgbox @hello 0x2
end

#org @hello
= Hello, my name is dshayabusa.

0x3

Spoiler:

Description:
Used for signs etc. No lock or faceplayer effect. Only shows the sign textbox when used on an actual sign.

Script:
#dynamic 0x800000


#org @start
msgbox @sign 0x3
end

#org @sign
= You are here

0x4

Spoiler:

Description:
A normal msgbox except for the fact that it does not close. Command closeonkeypress must be used to close it. No lock or faceplayer effect.

Script:
#org @start
msgbox @hello 0x4
end

#org @hello
= Hello, my name is dshayabusa.

0x5

Spoiler:

Description:
Used for Yes/No questions. No lock or faceplayer effect.

Script:
#dynamic 0x800000

#org @start
msgbox @question 0x5
end

#org @question
= Is this statement false?

0x6

Spoiler:

Description:
Normal textbox. Has no lock or faceplayer effect.

Script:
#dynamic 0x800000

#org @start
msgbox @hello 0x6
end

#org @hello
= Hello, my name is dshayabusa.

Thanks for all the help! I've deduced that its the trainerbattle 0x1 cmd that's causing the movement... I assume that it has a faceplayer call... I figured this out by trying to turn the sprite, just to have her turn back when the @before msgbox appears for the trainerbattle.

Is there a way to compare a variable based on whether it is higher or lower than a certain number?

For example..

if 0x4011 > 20 event happens

You can use the 'compare' command to do that easily. Here's what your example would look like with it:

compare 0x4011 0x14
if 0x2 goto @EventHappens

The first line is pretty simple, you just write the variable you want to use and then the value that you want to compare it to. The second line is tricky if you don't know what XSE's 'if values' mean. Here's a table that diegoisawesome has on the first page:

Lower Than (0x0)
Equals (0x1)
Greater Than (0x2)
Lower than or Equal to (0x3)
Greater than or Equal to (0x4)
Not exactly equal to (0x5)

Since I'm using 'if 0x2', the script will only move onto @EventHappens if 0x4011 is greater than 20 (0x14). Hopefully that all makes sense.

Hi, I'm trying to execute a code that allows me to evolve a certain pokemon in my party (I'm actually form changing it, but I have inserted a routine to skip the evolution sequence. The issue I'm having is forcing the game to specifically ONLY evolve the particular pokemon.

So far I have this code: (note that my issue isn't with the routine, but rather with making the game understand that I picked A certain pokemon and any other pokemon will not be allowed to evolve)

Spoiler:

#org @start
lock
msgbox @talk1 0x6 "If bulbasaur is in your party its going to evolve"
setvar 0x8004 0x1
special2 0x800D 0x17C
compare 0x800D 0x1
if 0x1 goto @have
end

#org @have
From here is where I'm having issues. I need the game to give me bulbasaur's slot number in the party so I can execute this code:
Setvar 0x8001 0x(whichever slot Bubasaur is in)
callasm 0x900000 (This will evolve the pokemon in that slot.)
end

So, yeah.. Basically I need the game to check if I have the pokemon, find which slot that pokemon is in and execute that ASM to evolve it... Does anyone have any information? It would be greatly appreciated. BTW I got the ASM from here if that helps..

I have a question. If I use special 0x9f to select a pokemon. How would I execute a script to basically say if the chosen pokemon is (let's say pikachu) perform this script. If it's not pikachu perform this script. Basically I'm wondering if special 0x9f stores the index pokemon of the pokemon u chose and if I can use a compare to set up 2 scenarios. I'm wondering which var it would load the index number to

 

[MobAcc]

Or better yet is there a way to script an event so that a certain pokemon MUST be the 1st pokemon in your party to proceed ? Like basically I want to put a pokemon at the front of your party and have a guy stop you unless that pokemon is the first one in your party. It's really important that it's the first one in your slot.

 

[SupKids]

Is there a way to prevent you from stepping on a tile unless you have at least one Pokémon? It's supposed to be like when Professor Oak stops you from going on route 1 in Fire Red/Leaf Green.

Is there a way to prevent you from stepping on a tile unless you have at least one Pokémon? It's supposed to be like when Professor Oak stops you from going on route 1 in Fire Red/Leaf Green.

You could use a level script triggered in the overworld for that (the green "S" tiles). Diego's covered how these work in this tutorial already, alternatively there's this post. You could use that in combination with a flag check for if the Pokemon menu has been activated (flag 0x828 for FR, 0x860 for EM) or the countpokemon command. Hope that helps!

 

[SupKids]

Thanks for your response! Your post helped me understand variables better, but I just ended up using flags like you suggested since the variables seemed to reset once I left the map and came back.

 

[Aelthir]

Very handy tutorial! I'm just getting started with scripting, and I'm sure I will be jumping back for keywords and values often!

 

[Nice-kun]

is it possible to combine apply movement script and trainer battle script? how?

 

[Pyxal]

is it possible to combine apply movement script and trainer battle script? how?

This is fairly simple. Just slam dunk a trainer battle command in a script where you want it to be. Do look at the main page of the thread. You will find alot of answers there.
