Development: The Follow Me Script

i have an idea it would take a while but work,
have a script on every tile that uses a flag to check what starter u chose then sets ow then makes the sprite turn your direction and move towards you once every time u move.

That idea's been thought of, tried, and failed... sorry.
I'm afraid this will have some ASM with it...

Maybe co-ordinate comparing will do?

An assembly first checks the current pressed button:

Up
Down
Left
Right and compare co-ordinates:

e,g: Left\Right, coordinate 0,1 from player, Sprite down.
Up, coordinate 0,1, Sprite down.

detects the sprite number in the map of a map that is set in a variable.

This is an example from Luminous Yellow.

'----------------' Extract
msgbox @1 MSG_YESNO
compare LASTRESULT 0x1
if 0x0 call @end
showsprite 0x10
setvar 0x7000 0x10
callasm 0xunsetyet
msgbox @3 0x6

'---' cut

#org @1
= Ok!\nYour RIOLU is allowed.\lWould you like him\lto follow you around?

#org @3
= Have fun~!
''--'' end

level script for houses

'---'
compare 0x7000 0x10
if 0x0 goto @end
showsprite 0x10
callasm 0xunset
'---'

I don't have the routine yet. T_T

All scripts copyrighted.

Couldn't you use getplayerpos, store the x and y in a variable, and then subtract one from the y var if the player's facing up, add one to the y var if the players facing down, etc. and then create the OW for the Pokémon in that position?

At least I think that'd work - it would depend on if there is a way on checking where the player's facing in a level script - I'm not sure if it's possible.

Then again, what do I know?

i think the simple faceplayer should fix that prob :)
ur gonna need the same amount of OW in the end :)

Of course there is a way to check which way the player is facing... But this script wouldn't make the Pokemon walk it would just make it appear behind the player, plus it wouldn't work when changing maps.

If you had bothered to check my script, you would see I had done exactly that. If you want to fix this, then you will need a way to activate my script in a way the still allows the player to move if you do not use the 'applymovement 0xFF @pointer' bits. The map to map script worked on my script, just as long as you placed an overworld on every map. I have managed to solve many of these problems, yet I am completely stumped when it comes to removing the loop.

That's your problem, if you remove the loop, the script will no longer work for you because of how you wrote it.
You'll need to make your script branch off once movement of the second sprite is completed, and end the script.
The other thing wrong, is that as soon as you do that, the script will most likely be really buggy... actually, I guarantee it will be buggy, and broken. And this script will take up some serious space in your hack. (The script itself, and then like 9 or more bytes for every map you apply it to.

Not to mention have you made a workaround for when the player jumps off a cliff?
What about running speed? (If you are running, the sprite won't change speed with you, it will cause you to stop moving for a second or two while it walks.)

Don't even get me started on biking... (Same as running, more severe.)

Flight would not be bad, except when you fly, you leave your pokemon behind momentarily.
Surfing? No way buddy, not only would the pokemon try to follow you in the water, but it would be left behind by one tile.

And what about interfering scripts?

There are simply too many factors in place for your script to work under ANY condition.
And besides, you require JPAN's patch for it, we try to find solutions for people that don't use it, so that it will be available to ANYONE.

This is a job for ASM, I'm only learning ASM at the moment, so I am of little use... I can read it, I just don't know exactly how to apply it.

*cough*Would be helpful if there was another ASM tutorial...*cough*

[EDIT] I just realized... How would your script work for the player walking down onto another map or from the left, Since (I assume) the sprite X/Y coordinates are stored in an UNSIGNED byte, wouldn't that mean that there can't be a -1 for your sprite to rest on? Or does it not require a signed byte? I have not tested this at all, but I knew it was a problem from the start.

(For reference, an unsigned byte has a range of 0 to 255, whereas a signed byte has a range from -127 to 127)

Actually, last time I checked they were signed 16-bit values.

I see... well, then i guess it may be easier to understand.

this is sumthing i found: http://www.youtube.com/user/Mohh2haxer#p/u/1/22lSulNBcE8 i know its only an OW tho

There are other issues too. What if the player is standing against a border (such as a cliff) but facing away from it? Wouldn't the Pokemon following you appear on the border? That wouldn't look very good.

Giga Universe said:

That would not be a problem. Even in my script which does not work properly, the script runs only on the move, not the face. So if you tap a button and the player changes facing, the follower does nothing. However, if the player moves - it moves. So therefore, your situation would not happen, as to change the follower so it would be on the border, you would have to step away from the border. Therefore, the follower would not be on the border. Basically, long story short - in the ideal script (even in mine which is clearly not ideal), your situation will not occur.

Oh, sorry. I assumed that you were basing it on the way they were facing. My bad.

FIRSTLY!
*BUMP*
Secondly
couldnt you edit the bike and running routines to check if i pokemon is following you and if it is speed that up aswell except with the bike make the pokemon go into the pokeball like in HG/sS?
thirdly
would it be a good or bad idea to make the pokemon walthrough-able so that if the player gets trapped the player moves to where the pokemon was and the pokemon goes to where the player was using the script?
so that is a few problems fixed, but i was thinking to fix the moving maps problem could u not place a script with an OW at the mouth of all the entrances so that the script at the mouth will cause the OW there to do the following? and also how would you hide the OW from the last map? my only problem... the only othe solution i have for fixing map to map would be instead of using connections how about a warp without an animation so it moves you to the correct place as if it was a connection but it wouldnt show like a black screen etc.

Yes Ive Tried Hundreds Of Times To Make Sucessful "follow Me" Scripts
i did not know that its back in heart gold and soul silver tho...:o

I have already an idea on what to do, but it includes big time ASM.

Like I said, it is the same idea from before, but with an improvement.

The ASM routine of the bike will be edited, so the variable I am using is set to zero, which is no Pokémon follow you around. (That includes both Mach and Acro.) How? Well, when you press the bike, variable XX is erased. After you dis-activate the bicycle, it calls the very script that allows the sprite of the desired Pokémon to appear beside the player according to the level of the map and the accessibility (C is accessible, but D isn't for instance, and if the player is at C, the Pokémon cannot warp to like 10. And if the player is on 0, the Pokémon disappears until the player goes on a level. Same for 3C and other relative levels.)

Running. Simply, change the done applymovement called by ASM after comparison and checking into a higher speed.

Flying: When you chose an HM to use, even Cut and Rock Smash, the Pokémon will be temporarily hidden. How? Well, fly needs a change in routine, and other simples will just have hidesprite 0x and showsprite 0x added to their main script. Common sense FTW!

Surfing: The routine will be edited just like Bike, Fly and Surf. Meh, meh.

When healing: The Pokémon will temporarily appear.

This'll need a routine to check maps, and also needs a sprite in each map and a level script. These can be done in advance. If you wish the sprite just to do exactly like HGSS without putting a sprite or a LS in each map, then we have to edit the game's engine.
