How do i make cylinder effect in a platformer

UnknownUser

Hello ! I have been working on my 2D platformer, how do i make a 3D Cylinder effect like this one in the video :

While the camera follow the character, the cylinder shape give the impression to rotate, as if we are inside a tower

Hi, and welcome to the forum! Your post was caught in the moderation queue. You'll just need to verify your account from the email we sent so that doesn't happen again.

In terms of that effect, you can mix 2D and 3D in Godot. So that background could be a 3D model and the players sprites. You can also do pseudo 3D with Godot but I haven't tried it and I don't know if it's flexible enough to fake a 3D cylinder.

In terms of how it was done in the original. Notice that everything in the background is identifiably modular sections. So you can warp and skew them as needed to get the pseudo 3D effect.

But as @cybereality said you can render a 3D scene into a viewport and use that as a background.

Hi cybereality ! Thank for the welcome, i am the CODIV-19, here to take over the worl....Oops sorry, here to learn more of the magic of Godot my friend xD

The Tileset where the player stand seem to be rotated while moving, to me it doesn't seem like a background, i will try to look more into the pseudo 3D

Do you know any tutorial ? I didn't found it on youtube

Edit Thanks for the thips Megalomaniak, when you say modular, what do you mean ?

Megalomaniak

As you said, tiles. As in each is a component on its own loaded into the scene and can be warped according to it's location in respect to the screen to make it seem like part of a cylindrical structure.

As for 3D in 2D there is an official demo, though it doesn't exactly use the 3D asset for a background there. https://godotengine.org/asset-library/asset/128

When you said component, you mean a scene node add like an object ? Thanks for the example

Megalomaniak

Yes. Though in case of the 3D asset rendered into viewport that shouldn't be necessary.

Should i also use canvas node too with the viewport node ? Until now i have been learning making classic Mario style game

Megalomaniak

I do not think it is necessary but depending on what exactly you are trying to achieve it might be useful?

UnknownUser

i never use canvas node before, so i wonder in what situation i might needed, maybe it can help me reproduce pseudo 3D

Megalomaniak

For clarity you mean CanvasLayer or CanvasItem? I assume former. Note that there's also the parallax background node.

It was the CanvasLayer i hear often in youtube tutorial, i never hear of CanvasItem, i already used parallax background node before but i wonder what is the difference between this node and CanvasLayer

Thanks again for the tips Megalomaniak
