You need a collision function -- something that will compare two rectangles and see if they intersect, here's some pseudocode: Function Collision(x0,y0,w0, h0, x2, y2, w2, h2) If x0 > (x2 + w2) Or (x0 + w0) < x2 Then Return False If y0 > (y2 + h2) Or (y0 + h0) < y2 Then Return False Return true End

This may be a bad idea, but I have an idea how you could test it. Put a large object in, something like: -- (10 meg) a[1024][10] get a RAM Monitor, remove/add/remove...the object and see if it's in and out. But I wouldn't have my computer running anything special so if it crashes or locks up/require...

I tried changing your tolerance level to 0.00000001, and it still worked, I'm thinking the math functions they're using is producing some kind of floating point error at some places. I appears you can minimize your own error by putting in a tolerance lower then .01, but I don't know how much perform...

I'm not entirely sure I understand the problem, could you attach a .love file? If the problem is finding a certain tile's x,y coordinates, couldn't you iterate through a loop in a load function and use that as the "map coordinates" for your collision reference?

I'm not sure I'm understanding your question, in what way will you be using c++, why couldn't you use a (*.txt) file and then input the parameters you need like:

inside the (*.txt) file

Code: Select all

blocknum: 1
image: 3
pos: 32 32
collidable: 1

blocknum: 2
image: 2
pos: 64 0
collidable: 0

Make or go to your config.lua file and add

Code: Select all

t.console = true

then print out what variables you need to see, for instance:

Code: Select all

print("Collision Function: " .. CollisionFunction( x,y,w,h,x2,y2,w2,h2 ) )

Correct me if I'm wrong, but wouldn't it be:

Code: Select all

velX, velY = player.body:getLinearVelocity()
-- Then just use the velY

?
