Official New URP 2D sample project: Happy Harvest - Download now

very cool sample project, here is my experience with it:

Unity version 2023.1.0b4

1. 2d feature doesn't have a version 2.0, I needed to update it to 1.0
2. ground normal maps are technically wrong/bad for the builtin 2d light system. As you can see, the lights cant illuminate in the +y direction(+y distance depends on the distance value of the light). I rotate the normals 60 degrees on the X axis to get proper normals for the ground tiles. My ground tile normals and the results look something like this:
3. Using a single colored mask or normal map is a waste of vram and performance; you dont need exactly matching size for normals/masks and main texture; a 1x1 texture for them is enough(Sprite_Tiles_Dirt_normal etc.)
4. soft shadows are not enabled at all, literally 1 slider to make the shadows 10x better
5. day night cycle + shadows system is amazing. I didn't even realize you could use 2d lights as 2d shadows!!!. Amazing.
6. rain droplets are amazing
7. transition scene could use a camera with a background image instead of just a black screen
8. fps was really bad in editor(<15 without fullscreening, ~20 with fullscreen; 5ms editor loop for some reason), smooth 60 in game(~40% gpu utilization on gtx 1060 3gb; max 30% cpu utilization on ryzen 3600)
9. overall code isnt perfect(really unoptimized update methods etc.) but it has some good utilities and systems(save system, stackable-single slot inventory system, scene transition system, 2d fade system, 2d day night system(amazing) etc.)
10. there isnt any adjacent rule tile in the project but that looks like a cool rule tile, it will definetely help with painting path rule tiles etc. into ground rule tiles
11. plant shader is very nice

 

bug: sometimes, after leaving the house I had about 20% gpu usage even with the zoom animation going on. After going left towards street_lamp (3), the usage skyrocketed to 50%. Going back towards the house doesn't reduce the gpu usage to even 30%.
After leaving the house:


After going left and coming back:

Really like the demo, would like to expand upon adding more mechanics like getting meat from hens & other animals. Also adding a quest system e.g. deliver some seeds or fruits to a person or market. I have one question would it work for mobiles devices? Main issue seems to me is mouse input which needed to be converted to touch.

 

m_CurrentWorldMousePos = Camera.main.ScreenToWorldPoint(Mouse.current.position.ReadValue());
how to convert this to touch, even i tried to make a virtual mouse pointer for interactions using virtual pointer script of inputs system but that did not work

 

Just exported it to ios device, click are not working as touch. I used inputs system on screen controls demo. Walk etc works while interactions are not working

 

This is a neat little demo and I think it's a great representation of where 2DLights and Unity is right now. Would still love Spritebased shadows in the future. It's nice to see Unity is making the Tilemap and data play together, I wonder if anything jumped out at them while doing this?

But also you've got a game breaking bug! It causes crops to become unharvestable if you ever go back inside the house. This is because:

1) CropInitializer is only called once because the crop data is then stored in GameManager, which is a persistent object.
2) However, the VisualEffect for each crop is stored in the outdoor scene when a crop is planted.
3) Therefore, when you leave the scene and reenter, GameManager will tell CropInitializer that a crop has already been planted there. The crop will not plant, so no VisualEffect is generated, causing an error on HarvestAt.

 

I test the demo on my android device. It work well on Snapdragon 8 Gen 1. But freezed on Snapdragon 710, when enter the outdoor scene.

When the demo freeze, in android logcat, it shows
Adreno-GSL <gsl_ldd_control:549>: ioctl fd 77 code 0xc040094a (IOCTL_KGSL_GPU_COMMAND) failed: errno 71 Protocol error
Adreno-GSL <log_gpu_snapshot:458>: panel.gpuSnapshotPath is not set.not generating user snapshot

Is there any solution to make the demo work on most devices? we really want to make a 2D game use this 2D Light system.

 

@eduardooriz is there any plan to push any new update for this demo yet. Why this demo doesnt have github as many other demos so that we can at least check out some of the experimental stuff?

 

unfortunately it does not work on mobile. How to fix please? Is it possible to get precise instructions?

 

Great example. Many tricks and resources to learn from.
I have question about NormalMap color. Neutral/flat color is considered to be #8080FF (0.5, 0.5, 1.0). In project, for tiles like dirt, grass, etc. is used color #7FE8C8 (127,232,200). My question is why not #8080FF?

 

That is the error I talked about here

Take a look at this example(camera at 60,0,45 rotation) for 2 isometric cubes(they are moved a bit off-center so they aren't truly isometric)

If the normals were prepared like the left side(without -60 degree rotation to "normalize" the normal map) you get the colors around #7FE8C8(wrong)
If you rotate the normals -60 degrees on the X axis, you get the actual correct values. You need to use the normals like right side cube because the camera in 2d unity is not rotated, hence when doing the normal calculations you need to treat the normals as if they were rotated -60 degrees

If the game was actually 3d and the unity camera was rotated 60 degrees to give an isometric look, your normal maps would indeed look like the left side.

 

Thank you venediklee. Now I understand and I'm impressed. Good job.
