Exhibition - Shadow Trails Demo look at this master piece

Yep, @msmalik681 shadow trail is the best option.
I just use it on a different way:
First, I've copied the shadow trail code to my animationscript:
Second, for memory optimization, I use a fowarder in the ondrawscript, so you need 2 files:
shadowon.c
shadowon_actual.c
I just use it on a different way:
First, I've copied the shadow trail code to my animationscript:
C-like:
//// ---------------------------------- SHADOWTRAIL - msmalik681
void shadow(int max, int delay, int timeout, int alpha, int tintm, int r, int g, int b)
{//animation script for shadow trails
void self = getlocalvar("self"); //Get calling entity.
int anim = getentityproperty(self, "animationid");//Get calling animation id.
//if any values null set defaults
if(max==NULL()){max=5;}
if(delay==NULL()){delay=20;}
if(timeout==NULL()){timeout=120;}
if(alpha==NULL()){alpha=6;}
if(tintm==NULL()){tintm=2;}
if(r==NULL()){r=0;}
if(g==NULL()){g=0;}
if(b==NULL()){b=255;}
//store all recorded data into entity variables.
setentityvar(self,"shadow.anim", anim);
setentityvar(self,"shadow.max", max);
setentityvar(self,"shadow.delay", delay);
setentityvar(self,"shadow.timeout", timeout);
setentityvar(self,"shadow.alpha", alpha);
setentityvar(self,"shadow.tintm", tintm);
setentityvar(self,"shadow.r", r);
setentityvar(self,"shadow.g", g);
setentityvar(self,"shadow.b", b);
}Second, for memory optimization, I use a fowarder in the ondrawscript, so you need 2 files:
shadowon.c
C-like:
#import "data/scripts/shadowon_actual.c"
void main()
{
actual_main();
}shadowon_actual.c
C-like:
//{max shadows} {delay between shadows} {shadow timeout} {alpha} {tintmode} {red} {green} {blue}
void actual_main()
{

Is it ok for me to add the EX mode if-else statements in this ondrawscript?
I want to have the time limit for the EX mode, basically, in these if-else statements will check for EX points.
Once the EX points have reached its goal, it would automatically activate the EX mode.
Once in the EX mode, the players only have about 30 seconds to a min before the engine automatically turns off the EX Mode by itself.
All of these would happen in the elapsed time inside
if(openborvariant("in_level")){)
I was wondering if this is to be using too much resource/memory.
Thank you
