I’m trying to implement a top-down Zelda-like enemy movement system. Consider a screen of x tiles wide by y tiles tall, each tile being 16x16 pixels. I’m not asking for code here. I’m asking for direction. I’m using Godot, but perhaps the answer isn’t engine specific. Should I use something akin to NavigationAgent2D? Or manual movement? Based on the requirements below what is the best practice for an enemy movement system? Requirements: Enemies can only move in cardinal direction...| Recent Questions - Game Development Stack Exchange
Goal: How can I best simulate headlight beams, in a night-time scenario, in Godot 4? The components I have are all sprite-based - a top-level car sprite, a shadow sprite (that is offset based on time-of-day, and changes), and a lane sprite (the D) that is attached to the car. This is on top of a road-bitmap, that will itself have its darkness/brightness adjusted based on time-of-day. The components: I can think of three ways that might work: Add a new sprite, (toggleable, with adjusted opacit...| Recent Questions - Game Development Stack Exchange

I have looked up ways to calculate DeltaTime in the past, but the 'solutions' seem to have my program be slightly jittery or not move things correctly. As far as I know, you would calculate it by finding the difference in time between the current and previous frame (Is this correct?). I have seen solutions find out DeltaTime with a fixed frame rate, but that is not what I am looking for.| Recent Questions - Game Development Stack Exchange
I'm making a game where players need to spell English words (including American and British English) using a limited set of 8 distinct letters, which can be re-used multiple times. How would I go about choosing those 8 letters to maximize the number of words players can spell? The words can be any length and have repeat letters. Proper names are OK too. I would think that using the four most common vowels (A,E,I,O) and the most common consonants (S,T,R & H - I believe), would yield the most w...| Recent Questions - Game Development Stack Exchange

In Godot 4.5 beta 6, I have a drag-and-drop situation where the data being moved between nodes is stored using instances of a custom resource. The resource instance is added to a property called data inside a scene called slot.tscn and set to be unique. Multiple slots are then added to the scene tree, and their data instances configured with different values, depending on what data each slot is supposed to hold. When the player drag-and-drops from one slot to another, the resource instances h...| Recent Questions - Game Development Stack Exchange
I’m a beginner developing a 2D game in SDL2 using C with a visual style similar to Geometry Dash (simple shapes, clean high-resolution graphics, not pixel art). I want the game to scale correctly to fullscreen on arbitrary monitor resolutions, keeping graphics crisp and sharp. I’ve found little guidance online about the industry-standard approach for this.

I see in noise functions a lot the function "&256" I think it's used to wrap a remainder from 0 again for values larger than 256. Is this what the function does? For example In c++ Int A = B & 256; What happens if I try using for example 300? Does & 128 work to wrap at 128 but 300 doesn't because it is not a binary power of 2? So only &2, &4, &8, &16, &32, &64, &128 ,&256 work to be wrapped but for example &300 doesnt? I understand this is a binary function| Recent Questions - Game Development Stack Exchange

I need to know if the Perlin noise code I'm making that will use the hermite curve needs values between 0 to 1 or -1 to 1 in its permutation table or whatever is correct. I read the hermite curve uses values between 0 to 1 but I'm not sure. This means the permutation table is 128 or 256 values between 0 to 1 so they're all floats or doubles. Im asking about the range so the output stays in range because the formula will probably equal very large values if you use values that are larger than i...| Recent Questions - Game Development Stack Exchange

Consider a scenario where an object's world position is x distance in magnitude away from another object's position, naturally you would just use trig to determine the hypotenuse of the vector between them... is it nearby?
