Not sure why you think a checkpoint makes it any easier than any other option like pressing a button or F2 or something. The hard part is more around what to save and load vs what starts the saving/loading process.

[YouGroove]

Let's say you have ennemies at screen and player and 3D effects on, if you wish ot save axect position , animation, state of each ennemy, player etc ... this is lot of work.

Just do like Uncharted 3, Halo 4, GTA5 and use checkpoints.

[Rick]

checkpoints have nothing to do with all the data you have to save. all a checkpoint is, is an area that tells your game to save the data it needs to, but you, the coder, has to decide on how that's done. checkpoints aren't magic saving things

[YouGroove]

@Rick: ok

Well about tutorials, it's all Youtube.

Why not including a link to code files ? I can't imagine watching Youtube and have to carefully watch and type all visible code on the video.

[Rick]

In my videos I more hope to show ideas on how things can be done than to be a code copying thing. Most of the scripts I have used for the tutorial have been very small and actually I copy from the wiki that collision script on most of them and just make small modifications. It's really about typing things out yourself, experiencing issues and fixing them to learn. I make these tutorials more for learning than to just give out scripts. If I wanted to do that I would just put them on the asset store like I have some other scripts, but these are more about learning and my thought process as I do this for others to see.

Id like to learn more about the player movement, like how to add crouch, headbobing and ect.

[YouGroove]

@Rick : it makes sense.

 

@Shirk :

You can do two ways :

- simulate it by just moving camera down for crouching and adjsut collision ; and doding a movement on camera for headbobbing

- animate a character for crouch , headbobbing etc ... and just place camera in front of head (adjust collision height when crouching)

[Shirk]

Ive been trying to figure out the headbobbing in the last few days, but cant get anything to work.

[YouGroove]

You need a 3D artist with you , or a coder, or both

( or just google images for "walk cycle" )

 

as you can see the head follows a familiar pattern ( stretched sin ) - simply adjust the cameras offset to the ground accordingly as long as the player is moving forward and set it to the normal/high height when they stop.

[ludwurks]

A tutorial on rounded edges (or rounded walls/corners) would be great. that along with some more advanced geometry using the in editor primitives/compounds

[Rick]

@ludwurks Hey, this is thread is more about gameplay (scripting) tutorials than art.

[Shirk]

Here is a simple tutorial for a crouch function. I wouldn't say its very good, but at least its a start for someone.

 

Open up FPSPlayer.lua from your assets folder and navigate to the function UpdateWorld around line 230. Right after the end of

if window:KeyHit(Key.E)

add another window.KeyHit for the crouch button (In this case I used C)

if window:KeyDown(Key.C) then
end

 

This checks to see if a key ( the C button) is pressed down within the window. In that add the following code

self.camera:SetPosition(self.entity:GetPosition(true)+Vec3(0,self.eyeheight * 0.5,0))

 

That sets the current cameras position to half the height of the players eye height.

Just under that add

self.moveSpeed = 2

 

This sets the current move speed to 2 (your speed may differ) so you don't walk as fast as you would standing up.

 

Now to check when the key isn't being pressed so you can continue walking at a normal speed.

if not window:KeyDown(Key.C) then
self.moveSpeed = 4
end

 

That almost looks like the code above, except for the addition of not before the window:KeyDown. This checks to see when the key is not pressed down, and sets the speed back to the normal walking speed.

 

Also, can anyone help me figure out a simple viewbobbing? I dont really know where to begin.

[Rick]

Got a fairly simple method for saving/loading entity data finished. Will be making a tutorial (with files) tonight. This one is pretty slick if I do say so myself . There is probably room for improvement but it should work on any platform once the others come about for 3.1, and it's non programmer friendly I think. Leadwerks could help out a little with providing some more info with things, but it works for now.

[Shirk]

That sounds awesome, how do you load and save though? Just hitting a button like F6 and F7? And I agree, I wish more tutorials would explain what everything is doing in detail, I don't like simple copy and paste scripts.

[Rick]

How you load and save is left up to you. I show a couple ways to do it via collision triggers (checkpoints) and an OnSceneLoaded type script, but there would also be UI ways if you had that.

[Kavex]

Wow your list is growing

[Rick]

Added Save/Load game tutorial to front page. It's processing now but should be done in 15 mins or so. Need sleepy now.

[Mordred]

Maybe a tutorial on how to create and use heightmaps in Leadwerks 3.1 would be cool too, even if the heightmapping tool is not from LE it might make the life lot's easier than modeling the terrain by yourself.

[Rick]

@Mordred This thread is more focusing on programming at this time. That in itself is a big task Maybe someone who has more art skills could start a thread for the art side? For now I'd like to focus on programming for this thread.

[Mordred]

Ah darn, sorry Rick, i remember that this was mentioned before already, but i forgot it Sorry 'bout that.

[YouGroove]

There is a lot on Youtube : just search them

[SeaHorseShooter]

Thank's so much for the save/load video Rick!! Really helped me out

[Rick]

np SeaHorse. It was probably my favorite one to do so far since it was a little more involved and interesting!

 

Everyone, please list out anything you'd like to see that isn't already on the front page and is programming related and isn't a huge system that would take hours to explain in a tutorial.

[shadmar]

Trails would be great, requires some kind of continious trainglestrip.
