Collision and OOP in lua - oop

Question

So I've made a basic collision system in love2D using basic OOP.
function love.update(dt)
player:update(dt)
for _, rect in pairs(randomRectangles) do
local collides,mtv,side = collider:collidesMTV(player,rect)
if collides then
print(side)
player:collide(collides,mtv,side)
end
end
end
mtv being the minimum translation to move the part when it collides and the side being the side it collides on.
The problem is, I want to be able to make it so in the player:collide function, shown here:
function player:collide(colliding,mtv,side)
if colliding==true and side=="top" or colliding==true and side == "bottom" then
self.Position=self.Position-mtv
end
if colliding==true and side=="left" or colliding==true and side == "right" then
self.Position=self.Position-mtv
self.Gravity=-0.1
end
if not colliding and self.Gravity ~= -0.95 then
self.Gravity=-0.95
end
end
I can make it so when it's NOT colliding, it sets the gravity back to normal, but if I add an elseif/else statement inside for when it's not colliding, it'll also do that if it's colliding with one block since there's 30 other blocks on the screen and won't set gravity to -0.1 since it'll be always setting it back to normal gravity, if that makes any sense.
How can I fix that?

Answer 1

Maybe simply extract the collision behavior outside of the collide method? Here's an idea:
function player:collide(colliding,mtv,side)
if colliding==true and side=="top" or colliding==true and side == "bottom" then
self.Position=self.Position-mtv
end
if colliding==true and side=="left" or colliding==true and side == "right" then
self.Position=self.Position-mtv
self.hasSideCollision = true
end
end
function player:computeGravity()
if player.hasSideCollision then
self.Gravity = -0.1
else
self.Gravity = -0.95
end
end
function love.update(dt)
player:update(dt)
player.hasSideCollision = false
for _, rect in pairs(randomRectangles) do
local collides,mtv,side = collider:collidesMTV(player,rect)
if collides then
print(side)
player:collide(collides,mtv,side)
end
end
player:computeGravity()
end
Dealing with gravity should be dealt with at the player level, not the individual collision's.
EDIT
Took direction into account and moved gravity logic into its own method.
