All language subtitles for 004 Cube Grid and Greyboxing[UdemyIran.Com]

As the next player ability.

I want to implement the wall slide and wall jump.

A problem we currently have, though, is that it's hard for us to test because we just pretty much

just duplicated the floor and put another wall here, but I actually want to have a better way for us

to build a small playground where we can test out new abilities.

And with Unreal Engine 5.0, something new was introduced, which is the cube grid that is perfect for

this.

So first just select the wall, the floor number two and hit delete on the keyboard.

Get rid of this and we're going to start to use Cube Grid to build a small level we can use for gray

boxing.

And gray boxing just means that we build the gameplay part of our level as a gray box without worrying

about what it looks like.

And once we made sure that everything works, we can start to actually put some time and make things

look better.

To open up the cube grid, we can just click here on the selection mode and go to modeling.

And this is a little bit hard to find.

You probably not think it is in this menu.

And with Unreal Engine 5.0 we actually got a lot of crazy modeling features.

Like a lot of things you would do in blender, you could also do in here now.

And as part of that we also got the cube grid.

And we're not going to worry about all of this other stuff.

This is very complicated.

This is something you're probably not going to need.

But cube grid is something that is very easy to use and you can get a lot of benefit from.

So just click here on Cube Grid.

Right now it is a little bit hard to see because we have the floor here.

But if you go to the side you can see that we have this kind of grid here on the side.

And this basically allows us to create blocks in on top of this grid.

Here on the left side, there's a lot of options.

There's a lot of things you can do.

But we're only going to cover the basics, the things that we actually need.

So the first thing I want to do is to create some new blocks.

So here's the player start I want to go to the left side of it and click this block.

And you can see it selected with the orange color.

Now.

And I just want to create a few blocks upward.

So to do this I can just pull and I can pull again and again.

And it's going to create more blocks that go upward.

And this is what I want to use to test the wall slide.

And if you made a mistake and you put too many blocks, you can just push push it down to get rid of

the blocks.

If you want to have some gaps, you can slide back and then pull right.

So now we have this gap here.

If you want to test something, maybe like shooting through a gap or having an enemy that kind of goes

through a gap, you can do that slide forward.

You go down again.

Right.

And then we can also get rid of the ones here.

And these are just the basic controls like this.

And we're not going to talk about corner mode or flip.

These are more advanced.

These allow you to make ramps and things like that.

And but more importantly these four buttons the pull push slide back slide forward.

There's actually keyboard shortcuts for these.

So if we go down here to the shortcut info you can see all of the keyboard shortcuts right.

So while this is selected if I press E I'm going to extrude or pull.

If I press Q I'm going to push down or get rid of the cube that I built to jump up or down.

I can hold shift and e to create a gap.

Right.

And then I can just press E to build again or shift and Q to go down.

And these are the very basic controls that we need to build things in our level.

You could also click on the side, for example, and build out like this and have a gap like this.

So all of these things are very easy to use and very useful.

But we're going to keep it very simple, right?

Like I said, I just want to make this a little bit bigger so we can test our wall slide and wall climbing.

Then I want to leave a gap of two cubes here and click on this cube.

And here I now want to leave a gap upward because I want to be able to walk in here.

So hold shift and click E one, two, three, four times maybe.

Yes.

And then just keep on pressing E like this and build up to the same height.

So now I want to be able to just walk to the left, jump to this wall and then jump to the other wall

like this.

But I think we actually need one more block here.

So I can just click here and extrude.

Right.

So now the character should be able to walk in here and we can jump here, here, here, here.

And I also want to just build a small staircase for the crab to put the crab on it.

And just here we can multi-select.

Just hold left click and select multiple ones and then press E to go up.

And just create another step here.

Just one more.

Right.

And this is just for the crab.

So we can test the crab walking left and right and not falling down a ledge.

But that is something for later.

I just wanted to prepare this little staircase.

And very important.

Before we exit out here we want to click on accept.

Otherwise, all of the changes we've made now are going to be lost.

So click on accept.

And now we just go back to selection mode and you can see this new cube grid tool output which we have

here.

Right.

And you could just drag this around right.

But just go back with Ctrl and Z.

But this is basically a mesh a static mesh in the world that the cube grid editor created for us.

And very important.

If you want to go back into the cube grid editor and make some changes to this, you always want to

make sure that this is selected first, right?

Select this the Cube Grid Tools output and go back to modeling.

Go back to Cube Grid.

And now we can just pick up where we left off.

Right.

I can just add something here.

Uh remove them some things.

Remove some things.

Right.

This works fine.

But if you don't click this first it's actually going to create a second static mesh.

And another one and another one.

And then you just end up with a lot of separated cube grids.

So again just if you want to have these connected just make sure always select it first before you go

back into the cube grid mode.

And this is it pretty much for the cube grid.

And you can play around with this more, build some more stuff.

But this is what we needed for the wall slide and the small ledge as the last thing.

We now just want to take the crab and we want to put it on top of the cube, this one here.

And we also want to make sure that the crab is centered.

Right.

Because now we are exactly on this line here.

We want to make sure the crab is kind of in the middle here.

So we can just drag it here around.

And I can see that, well it's -50 is going to be the middle.

So just right -50 in here.

And the player needs to be of course on the same lane as the crab.

So the player also just -50.

And now we're nicely in the middle of this cube.

Right.

You can see we're right in the middle.

The crab is also in the middle.

And now we can just like a collision is set up.

Everything is set up right away.

And we can test play jump heights and all these kind of things.

And then later once we have the wall slide, we can start to like wall jump up here.

And this is it for this lesson.
