Creating clones of the same physics body with different values tied to the same lever

Solar2D Lua Language
#1

Hello!
I’m brand new to the Lua language and pretty much programming in general, been getting along great but have hit a roadblock unfortunately.
I’m trying to create 100 physics bodies, all the same shape, colour etc. (basically clones of one archetype), but each with a different value or tag that I can reference towards, however without having to put for instance 100 chunks containing :

local newCard = display.newRoundedRect(80, 50, 150, 400, 3)
newCard.strokeWidth = 3
newCard:setFillColor(154, 80, 44)
newCard:setStrokeColor(0, 0, 0)
physics.addBody(newCard, “dynamic”, { filter=newCardCollisionFilter} )
newCard:addEventListener(“touch”, gameUI.dragBody )

into my code. Help on finding a way around this would be absolutely fantastic and greatly appreciated.
Thanks very much,

make a pseudo class containg that and then isantiate it in a loop… [import]uid: 50154 topic_id: 11514 reply_id: 41770[/import]

you can do something like below

[lua]local tags = { “1”, “2”, “3” } – you put your values/tags here

for i = 1, #tags do
local newCard = display.newRoundedRect(80, 50, 150, 400, 3)
newCard.strokeWidth = 3
newCard:setFillColor(154, 80, 44)
newCard:setStrokeColor(0, 0, 0)
physics.addBody(newCard, “dynamic”, { filter=newCardCollisionFilter} )
newCard:addEventListener(“touch”, gameUI.dragBody )
newCard.tag = tags[i]
end[/lua] [import]uid: 48521 topic_id: 11514 reply_id: 41805[/import]

Hello chinmay.patil!
Thank you very much for your help! Unfortunately I’ve hit another roadblock, I’m trying to add a joint to each of the flash cards that come up, e.g. I want the cards to pivot around a single point, but when I do this :

local tags = { “1”, “2”, “3” } – you put your values/tags here

for i = 1, #tags do
local flashCard = display.newRoundedRect(80, 50, 150, 400, 3)
flashCard.strokeWidth = 3
flashCard:setFillColor(255, 255, 255)
flashCard:setStrokeColor(0, 0, 0)
physics.addBody(flashCard, “dynamic”, { filter=flashCardCollisionFilter} )
flashCard:addEventListener(“touch”, gameUI.dragBody )
flashCard.tag = tags[i]
end

cardJoint = physics.newJoint( “pivot”, flashCard, lever, 150, 70 )
cardJoint.isLimitEnabled = true – (boolean)
cardJoint:setRotationLimits( -45, 0 )
a1, a2 = cardJoint:getRotationLimits()
the lever isn’t having any effect anymore. If you could help that would be great!
