i have used an shadow script in an game. The shadow works right but it dont chase the cars direction and it duplicates allways the shadow plane. does any1 know what i mean, and know how to solve this problem?

Thx for all answers!!!

hey! can you share that shadow script?

from math import sqrt

cont = GameLogic.getCurrentController()

owner = cont.getOwner()

def normalize(x):

length = sqrt(x[0]*x[0]+x[1]*x[1]+x[2]*x[2])

return [x[0]/length,x[1]/length,x[2]/length]

def cross(x,y):

return [x[1]*y[2] - x[2]*y[1],

x[2]*y[0] - x[0]*y[2],

x[0]*y[1] - x[1]*y[0]]

def dot(x,y):

return x[0]*y[0] + x[1]*y[1] + x[2]*y[2]

def mul(s,x):

return [s*x[0],s*x[1],s*x[2]]

def vecToMat3(vec,track):

z = normalize(vec)

dotprod = dot(z, normalize(track))

if abs(dotprod) == 1:

track.append(track[0])

del track[0]

x = normalize(cross(track, vec))

y = cross(z,x)

return [[x[0],y[0],z[0]],

[x[1],y[1],z[1]],

[x[2],y[2],z[2]]]

#at “ray” is the object that has an ray linked

#to the shadow plane(an car or the person…)

#at shadow is the shadow object

if cont.getSensor(“ray”).isPositive()==1:

HP = cont.getSensor(“shadow”).getOwner()

BHPosi = cont.getSensor(“ray”).getHitPosition()

BHNorm = cont.getSensor(“ray”).getHitNormal()

AFWD = owner.getOrientation()

FWD = AFWD[0]

BHOri = vecToMat3(BHNorm,FWD)

HP.setPosition(BHPosi)

HP.setOrientation(BHOri)

thanx man!

any chance of a simple demo of this? please?

lol i remember trying to fake shadow’s by using a few lights to emulate the shape of the topography of an object, but once i realized (duh!) lights cant be black i stopped

I reckon someone should just write a shadow stencil script. …what. it wouldn’t be that hard!!!

Hmm, it could be possible, but it would be very difficult, and I don’t even know if it would be possible!

I don’t know what’s wrong with the script, sorry
