[SCRIPT] Charge Attack in Megaman style

White Dragon · Sep 27, 2014

/*
* PARAMS:
* self = entity that performs a charge attack
* key = hold button for charge attack: "attack" or "special" etc..
* color1,2,3 = flashing colors. set it in RGB format like -> rgbcolor(0x43,0x00,0xDA)
* max_charge_time = time in frames of whole charge time (from min to max charge)
* atk_name1,2,3 = ATTACK NAME ex. "ANI_FREESPECIAL1" or "ANI_FOLLOW1" or what-you-want
* sound_fx = sound path+filename (OPTIONAL)
* sound_duration = sound duration time (OPTIONAL)
* flashing_ent = flashing entity (OPTIONAL)
* flash_frame_length = frames number of flashing entity animation (OPTIONAL)
* on_base_flag = if 1 you can perform a charge atk only on land else set it to 0 (OPTIONAL)
* first_atk_flag = if 0 you avoid the first attack. so only last 2 attacks are valid (OPTIONAL)

Example (script event):
script player_script.c

Code:

void main() {
  void self = getlocalvar("self");

  charge_attack(self,"attack",rgbcolor(0x00,0x26,0x88),rgbcolor(0x43,0x00,0xDA),rgbcolor(0x00,0xDA,0x0F),openborvariant("game_speed")*6,"ANI_FREESPECIAL17","ANI_FREESPECIAL21","ANI_FREESPECIAL13","data/sounds/frozen03.wav",openborvariant("game_speed")*0.2,"cflash",3,0,1);

This code is a basic script.
You can obviously change it to your liking.
Ps. Dedicated to O Ilusionista!

O Ilusionista · Sep 27, 2014

wow, you are my hero!!!!!!!

White Dragon · Sep 28, 2014

O Ilusionista said:

I made a small change.
Now you can enter the colors directly in the function as parameters.

O Ilusionista · Sep 28, 2014

"ANI_FREESPECIAL17","ANI_FREESPECIAL21","ANI_FREESPECIAL13" are the 3 levels, right?

White Dragon · Sep 28, 2014

O Ilusionista said:
"ANI_FREESPECIAL17","ANI_FREESPECIAL21","ANI_FREESPECIAL13" are the 3 levels, right?

Yes, it's an example.
ANI_FREESPECIAL17 is an attack that you perform without charge. if you dont want it, ~~you can put a comment on performattack~~.
if max_charge_time == openborvariant("game_speed")*6 (6 secs) every charge continue for 2 secs (6/3) because I divided the charge time into 3 times.
So you can perform ANI_FREESPECIAL21 after 2 secs and ANI_FREESPECIAL13 after 4 secs.

wait....
ADDED another param in the code and improved flashing entity section.
To AVOID the first attack (without charge) use the last flag (first_atk_flag).
Set it to 0 if you want to avoid the first attack (ex. ANI_FREESPECIAL17).
Changed PARAMS order too...

rafhot · Sep 28, 2014

thanks this will be very useful to me too

rafhot · Nov 10, 2014

now im looking for one variation of this script that keep the character in one charge animation and unmovable while holding the button and when release the button it shots one of those freespecials based on how much time it was holding

white dragon is it too hard to adapt this code to my case?

takuma in his holding /charging animation player do a command to activate his freespecial and he enters in charging/ holding projectile animation then when player release one of the three projectile variations will be played based on time he was holding the button

O Ilusionista · Nov 10, 2014

I would say to set the speed to 0, but this would bring some problems.
Why don't use a tosstime?

White Dragon · Nov 10, 2014

yes set speed to 0 (i dont like it) or better perform a charge animation setted to 0.
Then use a function that freeze all nemies and objects like street fighter by using:
changeentityproperty(self,"freezetime",openborvariant("elapsed_time")+pauseadd);
changeentityproperty(self,"frozen",1);

rafhot · Nov 10, 2014

thanks guys, i think i will dont need the freeze all enemies part.

i will just need a loop animation to the charging period like takuma holding his projectile and shaking, i alredy did it once using keyint based on crime buster athena once, i wil do some tests and try it here too

when you guys say set speed to 0 i dont know exacly where to change it
i will do some test to see if i figure it out eheh

changeentityproperty(self,"velocity",0,0,0);

O Ilusionista · Nov 11, 2014

There is a side effect that I noticed: when you set an enemy speed to 0 (on a grab move, for exemple) he won't walk anymore, because his speed is now 0.

Hey, I'm really beginner about Openbor.
I want to use this script but ... EROOR...

Property name 'y' is not supported by function getentityproperty.

If it's ok, Please tell me "How to use it".

aL BeasTie · Feb 20, 2015

make sure you have the latest openbor version.

betterbold · Sep 2, 2015

I solved the problems.

It's a great script !!
Thanks.

tayloong · Jan 11, 2018

I didn't understand yet how it works, I'm a little confused. Could you please create a demo?

KaiSSeR_SK · Apr 23, 2020

Hi all! I hope this is not a too stupid question. Well, I've found the script CHARGE ATTACK MEGAMAN STYLE (http://www.chronocrash.com/forum/index.php?topic=1877.msg24343#msg24343) but I have no idea about scripting and I don't know how to make it work on my project. I have been experimenting on my own without success. The last question asking for help was made in 2018 without response, and avoiding necropost, etc, I prefer make here the question. Thank you so much.

kimono · Apr 24, 2020

Hi KaisseR_SK, did you take a look at betterbold's Megaman project? He uses charge attacks and it works flawlessly:
http://www.chronocrash.com/forum/index.php?topic=4259.msg62396#msg62396

If you don't manage to create something like this, I can help you to set this special attack.

HI! Tanks for thanks for answering. I've searched, downloaded and tested many Megaman's mods, but it seems to me that this I have not tried.
Thanks again!

EDIT:
In MMan mod, works perfectly, but when I try on mine: "There's an exception while executing script 'updateentityscript' data/chars/TestChar/TestChar.txt
