GAMEPLAY - How to make a Video Game in Unity (E06) Video Lecture | Build a Game: Unity Tutorial (English) - Game Development

in this video we're gonna be making some
actual gameplay it's what it should look
like when we're done awesome so let's
get started so what we're going to be
doing here is pretty much creating a
level by hand using a bunch of prefabs
this allows us to really easily create
interesting levels and fine-tune each
part of the level to a good difficulty
setting the problem with this manual
approach is that you cannot have
infinite levels you're going to have a
start and an end point if you want to
create never-ending levels
I really suggest you watch my livestream
on creating a Dutch the blocks type game
in that video we randomly spawn
obstacles from a few spawn points
however making things procedural is a
bit more difficult it does require some
coding and unless you are very skilled
with it it leaves you with very little
customization when it comes to creating
more deep and interesting levels anyway
let's take our obstacle and drag it into
a project what we just did was create a
prefab of that obstacle prefabs are used
whenever you want to have multiple
objects of the same type in our case we
want to have a lot of different
obstacles in our scene what we can now
do is take this prefab from the project
and drag it in anywhere into our scene
the cool thing is that if we now go to
our obstacle and change the settings say
the size on the x axis you can see it
updating on all of the objects at once
I'm just going to undo that we can also
edit one of these objects individually
so it's like the first object here and
change the mass we can then go up here
and hit apply and it should now be
applied to all the other prefabs and we
can see indeed the mass has changed on
those as well remember to always hit
apply whenever you've changed something
on the prefab that you want to be
applied to the others again I'm gonna
put that back to two and hit apply the
first thing that we need to do is extend
our ground plane currently we can go for
a little bit and then we're going to
fall off of course there are ways of
making our ground plane follow the
position of our player one common thing
to do when creating endless-runners is
not actually move the player but instead
move all of the obstacles and
environment pieces closer to the player
as the game progresses this way we can
actually just have a stationary ground
element but in our case we want to have
some cool physics and that looks much
better if we move the actual player so I
think the solution here is a symbol as
just scaling up the ground let's take
the ground give it a scale on the Z of
say 10,000 let's also move it over on
the Z but set that to 4980 that should
make sure it begins in about the same
place as our player now of course we can
begin sketching out our level there are
a few things we can do to make that easy
for us the first one is getting the
right view in the scene view notice how
we have different axes up here we can
actually click on those to shift our
view to that axis so let's click on the
Y or we're currently in perspective view
if we click on the center cube we can
switch to isometric this flattens our
entire scene and allows us to set up a
level in kind of a 2d view you can also
go up here and disable stuff like skybox
fog and flares you can toggle all of
those on and off by simply clicking the
environment here so I'm going to toggle
those off the grid I'm actually going to
leave in here but if you go in the
gizmos you can disable that as well we
can also take our ground go up to layer
hit add layer and we can add a new layer
called something like ground or
environment we can then take our ground
plane and assign that layer now if we go
up to the layers toggle we can hit the
lock next to the environment this now
means that if we deselect our ground we
can't actually select it within our
scene being still selected in the
hierarchy of course but it makes it so
much easier to select the objects we
want in our scene so now we can delete
our two obstacles here take the first
one and kind of move it forward a bit if
we drag on the green square here it
allows us to move it only in the X and
the position you can of course go ahead
and move these in freehand but I prefer
doing things on a grid we can go edit
snap settings to configure how objects
snap to the grid I'm gonna put two on
the X 2 on the Y and two and the Z and
just leave scale and rotation as is we
can just close this now and that means
that if we now move this object and hold
down control it's going to snap to every
two units all right so let's begin with
this in the center and then press
control D or command T if you're on the
Mac to duplicate the object and move it
over while holding down control and you
can just repeat this process to create
an interesting level
[Music]
all right so you can see I've created a
tiny bit of gameplay elements here of
course I did this very quickly and I'm
not always the most created when it
comes to level design but you get just
how easy it is to place obstacles into
our scene you should of course pump this
up with a bunch of different kind of
objects we can put collectible coins in
here obstacles that move back and forth
stuff to jump over or go beneath there's
plenty of opportunity and the best thing
about it is just how easily we can play
tester let's try and hit play and see
how difficult this level is the first
thing that I'm noticing is that my
controls feel really really slow now
that's not really a problem with the
level that's more a problem with our
movement script so let's see what we can
do to edit that let's select our player
and double-click on our player movement
now currently in order to move our
player forward we're adding a force and
I think that works fine but when moving
to the right and to the left
it feels very non responsive that's
because when adding a force to an object
over time it slowly builds up momentum
and we then change direction we have to
wait for the object to build up enough
force to do so this is where force modes
come in nearly they actually allows us
to specify in which way we should add a
force and we do that as a fourth
parameter first we have the force on the
X then we have the force on the Y then
on the Z and finally we have the force
mode let's put a comma here and let's
input force mode dot we can go through
and read about what the different forces
do the standard one is force which adds
a continuous force to the rigidbody
using its mass the one that we want is
velocity change this directly edits the
velocity of the object and it completely
ignores its mass so make sure to add
this to both of the add for statements
let's now save and hit back into unity
and I know by experience that when using
velocity change we need much smaller
numbers I think something around a
hundred should be fine so if we now hit
play we can try that out it already
feels much more responsive but I think
it could be better one thing we can do
to make the movement feel more snappy is
up the drag drag is basically air
resistance so the higher the drag the
more quickly our object is going to be
stopped by air that also means that we
need to amp up our forces in order to
move at the same speed but it should
make everything feel it more responsive
because the object is quicker just
slowed down so let's up the drag to
something like 1 let's leave the same
side wave force let's actually put our
forward force up quite a bit let's try
it out at 4,000 if we now hit play
everything feels so much better I think
is a good forward force and I think our
controls feel really fluent by the way a
cool shortcut is that you can play the
game by hitting ctrl P or command P if
you are on the Mac so the level already
feels pretty fun it's not too hard to
see that this particular part is a bit
too difficult so that's just going here
and maybe add a tiny bit more distance
between the first obstacle and the next
one and we'll do the same thing with
these let's try it out again much better
the final thing that I wanted to add in
this video is FARC currently we can see
all the objects no matter how far away
they are that's not too pretty and it
also makes the game feel a lot less
interesting the neat thing about this
game is that it feels like the obstacles
are coming out of nothing and you never
know what to expect well we know but the
player shouldn't so let's go undo window
and select lighting we can then take our
lighting panel and darken over here by
the inspector maybe give it a bit more
space there are a bunch of settings here
to play around with stuff like the
intensity of our ambient light how to
calculate shadows and reflections and
finally we have the FARC let's go ahead
and enable that
let's also expand it this allows us to
set a color of a fog you can choose
pretty much any color you'd like and
definitely get interesting with this but
I'm just going to go ahead and use the
color picker to get the color of our
background that makes it feel like
everything is blending in towards the
sky we then up the density a bit I'm
gonna set it to something like point
zero two so now if we maximize our game
view by hitting shift space press play
we can see that our game actually starts
to feel like a game the level is
currently really short though so I
definitely recommend creating something
a bit larger and again you have most of
the stuff in place here to create
procedural levels don't be scared to
experiment that was pretty much it for
