Collision

Solar2D Lua Language

Hi everyone,

I’m making a simple game but I have a problem:

-My jet needs to explode when it collides whit a mine, this works but now i have coins and when the jet collides with a coin in needs to add 1 point. 

-How do i make it so that when my jet collides with the mine it explodes and when it collides with the coin it adds a point?

code:

function onCollision(event)

    if event.phase == “began” then    

    if jet.collided == false then

    timer.cancel(tmr)    

    jet.collided = true    

    jet.bodyType = “static”

    explode()

     end

    end

end

Wrong section - it’s question about Corona, not Lua

It is a question about LUA, because the collision event doesn’t matters :wink:

But back to the question, you should give your mines and coins “names” so you can identify which one you are hitting in the collision event.

For example:

local coin = display.newImage("coin.png", 0, 0) coin.name = "coin"   function onCollision(event)    if event.phase == "began" then         if event.other.name == "coin" then           --add point to your counter        elseif event.other.name == "mine" then           if jet.collided == false then              timer.cancel(tmr)                  jet.collided = true                  jet.bodyType = "static"              explode()          end       end    end end

Hope the helps.
