[Character controller problems]

Honestly, if I wanted to make my own collision system, I wouldn't use Leadwerks.

[Character controller problems]

#1 is a design decision. If you would like this to be changed I can consider it.

I understand that it's more realistic, but there should be a way to work around that. Like another maxacceleration parameter.

 

 

#2 is diffuicult to judge. How else would this work? What exactly are you describing?

Have you played Volgarr the Viking? This is what I'm trying to make. In this game you can't control character in the air, but you instantly change speed when using double jump. This includes horizontal and vertical speed. If you are falling down for a few seconds you gain speed, but when you use second jump you instantly get positive vertical speed which wouldn't happen with simple AddForce. Same for horizontal speed.

 

It's like calling SetVelocity(0,10,0) the first frame user presses a button, but then letting physics engine to calculate everything.

 

 

I have recorded a short clip to show this

 

 

Basically, I could use SetVelocity for both, but it doesn't work with character controller. Can you make it work with it?

 

 

The tradeoffs are inevitable and this is why I coded my own in my last tournament entry. Not to say that there aren't solutions to your problems but I don't know any.

 

That said, I thought SetVelocity did work on character controllers. I could have sworn I used it to push back enemies in the past when they were hit.

 

Edit: it was probably AddForce.

Pretty sure it was AddForce, SetVelocity isn't working for me right now. Did you use rigid body in your game? What did you do with bouncing? I can't launch your game because it starts with too high resolution for my monitor.

[Character controller problems]

I'm making platformer and I have two problems with character controller and SetInput.

 

1: When walking on the ground movement speed changes instantly, but when in midair it changes very slow. I need my character to instantly change direction while in midair.

 

2: Jumping applies force instead of instantly changing speed. Again, I need this to be instant.

 

There wouldn't be problems if SetVelocity worked on character controller, but it doesn't.

 

I can't use rigid body because it bounces on collisions and there doesn't seem to be a way to disable that.

[Problem with Z-sort and render to texture]

Same happens when using buffer like this: http://leadwerks.wikidot.com/wiki:render-to-texture-security-cam

Is it a bug? Josh, can you look into it?

 

[fire prefab]

Use a regular particle system with your fire sprite sheet and uv animation to the size of your sheet. Like in this tutorial http://www.leadwerks.com/werkspace/page/tutorials/_/particle-emitters-r10

This way you will also benefit from new soft particles.

[fire prefab]

Use particle emitter for this, it also has uv animation.

[Need Help With Basic Collisions]

entity:Translate isn't supposed to work with physical objects, it will brake the simulation. You should use AddForce or PhysicsSetPosition.

Use methods from Physics part http://www.leadwerks.com/werkspace/page/api-reference/_/entity/

[Leadwerks 4.2 RC4 Flashlight causes alot of performance hit]

I have a better controls in my game with 120 FPS than with 60.

[Transparent object]

You want half transparent model? You can set it's material mode to Alpha, but it won't work with lighting. Maybe this can help you http://www.leadwerks.com/werkspace/topic/12091-dissolve-shader/

[Problem with Z-sort and render to texture]

Material with Z-sort enabled works incorrectly when rendered to a texture. See the screenshot.

Green and grey materials are regular, blue mat has z-sort enabled. Right part of the image is rendered normally, left part is rendered to a texture and drawn on the context.

 

 

You can see that blue cube on the left is visible through the grey cube. I need to have z-sort enabled for my particles with UV animation, but it makes them visible through the walls.

[Get Specific Entities In An Area]

No, but you can create an actual model box with the same size.

[Get Specific Entities In An Area]

It's a box, you know it's center and size, that's it. http://www.leadwerks.com/werkspace/page/api-reference/_/aabb/

[Visual Studio 2017]

Wait, I thought Leadwerks doesn't work on XP? It does with new VS or you are talking in general?

[Improve load times when changing maps]

Thanks! I was always wondering why restarting the map is so slow.

[How to load tga file and run animation sequence]

It's easier to just make a sprite sheet and particle emitter with UV animation or Shadmar's fire shader.

[SetRenderTarget (to texture) strange behavior?]

Yes, we found that in another thread http://www.leadwerks.com/werkspace/topic/15068-how-to-change-the-size-of-the-texture-resolution/

I guess this is correct behavior, you can just hide that model anyway.

[Cap Framerate (Without VSync)?]

It still causes input lag, so no benefits.

[Monthly Script Challenge Nov 16]

Just a small teaser to keep you motivated

[window:KeyHit strange problem]

this code does not work

if window:KeyHit(Key.H) then
if self.room == "Room1" then ... end
if self.room == "Room2" then ... end
if self.room == "Room3" then ... end
end

This is the correct way. You check for key exactly one time every update and only then check other conditions. If this is not working then the mistake is in other part of your code which we don't see.

Maybe you don't check for trigger collision if key isn't hit? Those two checks should be independent.

 

If you need to flush one key you just get it's state:

window:KeyHit(Key.H)

H key is flushed until next update.

[window:KeyHit strange problem]

This won't work I tried.

It does for me, your mistake is somewhere else.

[window:KeyHit strange problem]

Just do this

local hHit = window:KeyHit(Key.H)

if self.player_Inside_Room and hHit then

System:Print("Yay!")

end

[window:KeyHit strange problem]

Just make sure you check for key press every update and use this information only when needed. Don't put it inside other if statement.
