A quick tute on how to use the physics engine in your project. http://codeatuts.blogspot.com.au/
It is very easy to use once you understand the functions available.
As usual, comments welcome…
how do I make the object fall at set intervals from different x positions.
@veeeralp: as follows (from Minesweeper) in the Main class -
draw()
if gameState ~= stateMenu then
-- reinitialise variables if not in the Menu screen
menuTime = 0
menuMineCtr = 0
end
if gameState == stateSplash then
splashScreen:draw()
elseif gameState == stateMenu then
drawMenu()
elseif ...
end
end
drawMenu()
menuTime = menuTime + DeltaTime
if menuTime > 1 then
-- create a mine physics object at a random spot at the top of the screen
createCircle(math.random(50, WIDTH - 50, HEIGHT, 32)
-- keep track of how many mines we have created. In retrospect I could have
-- just counted the items in the PhysicsDebugDraw bodies table.
menuMineCtr = MenuMineCtr + 1
menuTime = 0
end
if menuMineCtr > 50 then
-- reset the physics body table and re-initialise
-- I originally put this in when the ground was there.
-- I'm not sure how many objects you can have on the
-- screen at once without slowing down appreciably or
-- eventually crashing due to low memory. 50 seemed safe.
menuMineCtr = 0
physicsDraw:clear()
end
physicsDraw:draw()
-- do the rest of the menu drawing...
end
@Reefwing I’m getting really low fps when I add the physics objects. Any ideas? I’m using a modified version if your menu state with six buttons.
@Reefwing. Nevermind got it. When I make the physics objects fall down, they are colliding with a physics object in another state. Any help? It’s being drawn but is invisible. I need to be in the run state only but it only needs to be called once. Not once every frame. So what I’m asking is is there a way to call do an initial setup for a gameState. Right now I’m calling it the regular function setup
