Re: First game, struggling with camera/movement

I'm printing out the camera coordinates like you suggested, and they seem to change with the s key. But nothing on the screen moves. I feel like I'm missing some basic thing. Here's the code, and I'll attach a .love which illustrates the issue function love.load() Camera = require "lib.camera" viewx...

Re: First game, struggling with camera/movement

Sorry, just a typo when I was writing out the question. In my code it's correct. I can run the game, get no error messages, but pressing the keys does nothing.

First game, struggling with camera/movement

Basic question on how to move the camera around. Using hump camera. Here is what I have so far. Pressing "d" or "s" doesn't move anything. Also, cam doesn't seem to want to "start" at coordinates 100, 100 for some reason, but I don't get an error. function love.load() Camera = require "lib.camera" v...

hump camera return

The last block of code from the hump.camera module: -- the module return setmetatable({new = new}, {__call = function(_, ...) return new(...) end}) I'm fairly new to OOP and metatables, and can't parse what the point of this code is. So it's returning a table with the new method defined in it..and t...

Re: Need to change image each frame

Just to clarify, so when we use love.graphics.newImage, is it not caching anything into system ram, it's uploading directly to the vram?

Re: Need to change image each frame

Is there any way for love to display an image from a memory region of my choosing? I'm assuming it's caching a copy on it's own? I would rather it just reference mine directly if possible.

Re: Need to change image each frame

Unfortunately for my needs that method would be too slow like you said. The image:refresh() method looks promising though! It seems to be working at least 100x faster than a full graphics.newImage call. thanks!

Need to change image each frame

I need to generate an image, and render it each frame. This is for a particle simulation with lots of moving pixels. I put love.graphics.newImage under love.update and while it did reload the image each frame, it was at an unusable framerate. Would it be possible to load a new image once - then mani...

Re: Favorite way to store next loop state?

I was thinking about that, but if the condition results change literally every frame, it ends up being option a roughly 50% of the time, and option b 50% of the time. Won't that royally screw up any sort of branch prediction the cpu is trying to do? Is there a way to toggle the tables without using ...
