BeDieSim - a 3D Train Simulator

Alex88

Hello together, I want to show you some pictures of my project called BeDieSim. It is a train driving school game for real german train driver. Unfortunately I have some issues with the 3D performance so the project slowed down. The graphic is not the best, but the game should run on businesses PCs without a good graphic card. ToDo: - fix the performance issues - add the complete logic of the game <img alt="" src="http://alot-entertainment.de/BeDieSim01.jpg" height="453" width="750"> <img alt="" src="http://alot-entertainment.de/BeDieSim02.jpg" height="453" width="750"> <img alt="" src="http://alot-entertainment.de/BeDieSim03.jpg" height="453" width="750"> <img alt="" src="http://alot-entertainment.de/BeDieSim04.jpg" height="453" width="750"> <img alt="" src="http://alot-entertainment.de/BeDieSim05.jpg" height="453" width="750">

Hello,Great project,looking nice....Yes, we have to wait for better 3D to version 3 G:I wonder how you create terrain,how large are landscape areas? any LOD?

Alex88

Hehe, the terrain is just a flat plane with a grass texture. ;)At the moment the track is around 6 km long but I think I must reduce it.I use a lot of sprite3d or very simple meshes to save performance.

Hi Maybe you can post the project here so we can have a look and give specific advices.Otherwise I would say try to use level of detail and split the terrain into let's say 6 chunk of 1km that way you can only display two or three chunk at any given time.How many fps do you have?  The scenes seems very basic.Sam

Alex88

Your idea to split the terrain in 1km parts is exactly what I have already done. ;)My next step is to merge the wooden sleeper texture with the crushed rock texture because at the moment each wooden sleeper has 4 separate vertices.The frame rate is not the problem. I have between 59 and 60 fps but when you drive with a constant speed the game often stuck for a millisecond and this is very annoying.

@Alex88 Are you using physics (kinematic body)to move the train?  If so, periodic stuttering has been noticed for some time now when using them :(. Could be causing it.

Alex88

Hallo 2D||!2D, this is good to know but at the moment I use just a flying camera and a very simple script for the train. Maybe I use to much sprite3d or maybe it is a bug in godot.

extends Camera var Position = Vector3(-2.5, 3.5, -320.0) func process(delta):         if Input.is_action_pressed("ui_up"):         Position.z += 30 delta     elif Input.is_action_pressed("ui_down"):         Position.z -= 30 delta         if Input.is_action_pressed("ui_left"):         Position.x += 5 delta     elif Input.is_action_pressed("ui_right"):         Position.x -= 5 delta         set_translation(Position) func ready():     set_process(true)

</blockquote> The least optimal choice possible, can't cull triangles that could be behind hills and such. Buildings could help though.

Looks nice, and for some strange reason reminds me of Euro Truck. Could you also put up a shot showing your train?
