Main character in physics world - avoid rotating

Games
#1

Hi,

I am having a character in my gameworld that uses physics. But I don’t want him to tumble around when he hits something that he is allowed to.

Any suggestions on how to achieve this?

Hey

I’m pretty sure you can use “obj.isFixedRotation” to acheive this, though haven’t tested it myself.

Perhaps someone else could chime in?

have a function on enterframe that keeps the hero’s rotation zero

[lua]local function stopHeroFalling()
hero.rotation = 0
end

Runtime:addEventListener(“enterframe”, stopHeroFalling)[/lua] [import]uid: 79135 topic_id: 15546 reply_id: 57416[/import]

The above method will work fine. But another way that will use less memory and avoid using a runtime as spider said

[lua]obj.isFixedRotation = true[/lua] [import]uid: 39088 topic_id: 15546 reply_id: 57425[/import]

A good suggestion Andrew but as skilistican6 suggested, that one line will be more efficient and works perfectly to keep your hero (or other objects) upright. [import]uid: 52491 topic_id: 15546 reply_id: 57471[/import]

Thanks, that was a easy way to do it :slight_smile:

Hmmm, it seems to work as it should but if I rotate the object by code - it start to tumble around again?

player.isFixedRotation = true  
function leanBackward()  
 transition.to( player, { rotation = -20, time=1000, onComplete = leanBack } )   
end  
  
function leanBack()  
 transition.to( player, { rotation = 0, time=800 } )   
end

Any suggestion on how to solve this?

I did not know about .isFixedRotation.

[lua]player.isFixedRotation = true

function leanBackward()
transition.to( player, { rotation = -20, time=1000, onComplete = leanBack } )

end

function leanBack()
transition.to( player, { rotation = 0, time=800, onComplete= function() player.isFixedRotation = true; end } )

end

I just tested this and it worked as intended. (Version .591)

Do you have sample code you can share to test with? [import]uid: 52491 topic_id: 15546 reply_id: 57722[/import]
