transitions allows you to change values smoothly (from one value to another), over a given duration
you can animate the changing of position,size or color of object smoothly, rather than linear fashion
this website show how transitions work
//lerp_ease(a,b,amt,v1,v2,...,vn);
var pp,amt,num,a,b;
amt=argument2;
num=argument_count-2;
pp[0]=0;
pp[num]=1;
for (a=1; a<num; a+=1)
pp[a]=argument[a+2];
for (a=num; a>0; a-=1)
for (b=0; b<a; b+=1)
pp[b]+=(pp[b+1]-pp[b])*amt;
return argument0+(argument1-argument0)*pp[0];
this is a lerp script but can make so many transition
depending on how you enter arguments
lerp_ease(a,b,amt) //Linear
lerp_ease(a,b,amt,0) //In Sine
lerp_ease(a,b,amt,1) //Out Sine
lerp_ease(a,b,amt,0,1) //InOut Sine
lerp_ease(a,b,amt,0,0) //In Cubic
lerp_ease(a,b,amt,0,0,0) //In Quart
lerp_ease(a,b,amt,0,-0.5) //In Back
lerp_ease(a,b,amt,1.5,1) //Out Back
lerp_ease(a,b,amt,0,-0.5,1.5,1) //InOut Back
lerp_ease(a,b,amt,1,5,-3,0.88,3,0,1.07,1.07,0.99) //elsestic
//...
//...
example of using
//execute every step
//tim_now start with 0
if tim_now<=1
{
x=lerp_ease(str_val,end_val,tim_now,0,1);
tim_now+=0.02;
}
