full 3d space flight simulator in PICO-8

controls

roll - x/c
pitch - up/down (not inverted)
yaw - left/right

unfortunately the area you can explore is not very big in v1.0 and you can continue to fly out of bounds. Once you reach the edge of the stars, just turn around.

go on to explore the stars!

Modular functions

Wed, 09 Dec 2020 10:27:21 UTC

Here is a series of functions that are designed to be easily inserted into any project!
Each should be well commented and has a working example. comment if you have any questions!

add a mouse function quickly!

move towards a target with a normalized speed (diagonals are not faster!)

updated gpio library for (significantly) less tokens. now available for commercial use.
enter the pin (0 to 127) and return the hex (0x5f80 to 0x5fff) with get and set functions
old version included for posterity

covers rect collisions and map flags; circ collisions are in lookatlib

grid based path finding using A*

Collisions from tables

Collisions From Tables

by Ender42

[Click to Play]

I could easily find a tutorial on how to make a bounding box collision function online, but I could not easily find an example of iterating through a table to test for collisions, so I made it myself in hopes to help new programmers.

-- collision example
-- andy c

function _init()
 -- create player object named block, each object in this example will need an x and a y
    block = {}
    block.x = 64
    block.y = 64
    -- create 6 walls
    walla = {}
    walla.x = ceil(rnd(120))
    walla.y = ceil(rnd(120))
    wallb = {}
    wallb.x = ceil(rnd(120))
    wallb.y = ceil(rnd(120))
    wallc = {}
    wallc.x = ceil(rnd(120))
    wallc.y = ceil(rnd(120))
    walld = {}
    walld.x = ceil(rnd(120))
    walld.y = ceil(rnd(120))
    walle = {}
    walle.x = ceil(rnd(120))
    walle.y = ceil(rnd(120))
    wallf = {}
    wallf.x = ceil(rnd(120))
    wallf.y = ceil(rnd(120))
    -- add the walls to the wall table
    walls = {walla, wallb, wallc, walld, walle, wallf} 
-- here's an inspirational quote: "wall-e" - wall-e
end

function collision(wall)
-- basically if it overlaps on two axis, it's a collision
    if(block.x < wall.x + 8 and 
        block.x + 8 > wall.x and
        block.y < wall.y + 8 and
        block.y + 8 > wall.y)then
        return true
    end
end

function _update()
 -- basically, move the coordinate, and test a collision for every object in the table. 
 -- if any of them return true, move back the coordinate to where it was
    -- left
    if (btn(0) and block.x > 0) then
        block.x -= 1
        for i in all(walls) do
            if (collision(i)) then
             block.x += 1
            end
        end
    end
    -- right
    if (btn(1) and block.x < 120) then
        block.x += 1
        for i in all(walls) do
            if (collision(i)) then
             block.x -= 1
            end
        end
    end
    -- up
    if (btn(2) and block.y > 0) then
        block.y -= 1
        for i in all(walls) do
            if (collision(i)) then
             block.y += 1
            end
        end
    end
    -- down
    if (btn(3) and block.y < 120) then
        block.y += 1
        for i in all(walls) do
            if (collision(i)) then
             block.y -= 1
            end
        end
    end
end

function _draw()
-- iterate through the table and draw a blue square for each block. draw a red square for the player
    cls()
    spr(1,block.x,block.y)
    for i in all(walls) do
        spr(2,i.x,i.y)
    end
end
