[jME Tutorial 2-2] Introduction to Materials in the jMonkeyEngine Video Lecture | jMonkeyEngine Shader Tutorial: A Complete Tutorial - Game Development

all right to start us off I'm going to
create a new project with a new project
face it game going to cool this shader
tutorials again to open the source
packages folder my game package club
main Java and as you can see there's
already a unshaded material definition
here for our box geometry so shift f6
and show you what this is what the
unshaded material definition was
now to make it a little bit better to
play fair instead you'll help
demonstrate it because i'm going to show
you the two probably the most common
ones which are unshaded and light in the
control shift I to input the sphere and
then control space to get a construction
argument some points22 radius bring slow
kid good local systems where is look at
five six I'm going to untape vehicle
sank because frame rate decreases a lot
what i'm using my screen capture program
so they look like also going to like
increase the movement speed so i can
move around the virtual space lot easier
rotation speed okay so what is a
material the material in the je manque
engine is basically a way to talk to the
shader a higher level so to speak so it
takes care of the vertex and fragment
shaders for use in it we have to worry
about it and you can change the way the
shader works by putting in these
arguments sure what to call them so you
have like set color set flow boolean
matrix texture filled out a color map
the ones like that and I'll show you
these
the lighting material definition which
is the next most common one common Matt
deck lights lighting JD if you want to
find out what you can actually use of
these I'd suggest go into their
materials tutorials their wiki page on
the game and kyndra website so i can set
a few colors here i can set them and be
in color values blue is sad the fuse
also going to set that as blue and you
can set base specular color which makes
up all three of these make up the phone
lighting model and sort of course green
and there's a few other ones I want to
set was a boolean and if you aerial
colors I don't that's right true this
makes it so when I use my lights it does
drag it's like thunder palette so I
don't really I don't really want to use
the color of the light I want to use the
colors I set in the lighting material
definition and only I can change to
shine this let's float shiny move this
over face belly pull up five bungalow
create another geometry will use the
same sphere mesh though so I can reuse
that Scottish geometry
that's the same a little any matter
touch that to reload ready to be
attached material to that children sit
here ah so I've got bit of a cold no I
need to move that and except open
translation to move it to the right for
help in RX sweet you can probably see
those are quite a big difference between
this floor and under shaded mattel
definition on the laughs and this
awesome sweet one on the right of course
the one on the right is going to take a
lot longer to compute all the fragments
on it what else can I do not make sure
of course there's a few others there's
like this terrain ones for the particles
like a colored texture wanna think which
basically what you can do is set color
with it and that will probably be our
first real introduction to shaders
as I'll show you that one okay but I
guess I'll should show you what shaders
look like already how they look like but
the code that goes into making i'll
probably do the unshaded that's your
definition I'll do that there
