How to move the coordinates of an object on collision.

#1

Hello I need to know how to make the coordinates of an object on collision. If you have an idea that would be great. Thanks! [import]uid: 44060 topic_id: 8673 reply_id: 308673[/import]

Not sure how u want it done, but you can use transition.to or use the Run time.

[lua]local object

local oncollide = function (event)
if event.phase == “began” then
local moveTran = transition.to(object, {time=1000, x=200, y=160})
end
end

object = display.newRect(0,0,50,50)
object.x = 50
object.y = 50
object:setFillColor(255,255,0,255)
Object.collision = on collide

– maybe this might help. I haven’t tested this. [import]uid: 12455 topic_id: 8673 reply_id: 32585[/import]

No im sorry but that didnt quite do the trick but what im looking for is that when a balloon gets close to another balloon it changes corridenets and moves away or into the other balloon. Any ideas. [import]uid: 44060 topic_id: 8673 reply_id: 32742[/import]

In your collision function you can change coords instantly.

Say that you wanted the red balloon’s coords to change, inside your function simply say;

[lua]redballoon.x = 100
redballoon.y = 100[/lua]

Obviously replacing “100” with your own coordinates.

Is that what you are wanting to do? When you say you want to “make the coordinates” I’m not totally sure.

try applyforce or impulseforce. Unless you want the balloon to move at a constant speed, then you’ll have to use Runtime or transition.

hope this help. [import]uid: 12455 topic_id: 8673 reply_id: 33685[/import]

Hello

I’ve been trying to do the same thing - but with little success:

http://developer.anscamobile.com/forum/2011/04/22/function-causes-crash

Peach, that doesn’t work - I get the following error message:

“ERROR: Cannot translate an object before collision is resolved”

There are quite a few posts about this not working on the forums - so I’m stuck at the moment! ;-( [import]uid: 45932 topic_id: 8673 reply_id: 33818[/import]

I would suggest trying a short timer before attempting to perform the function, I had to add a timer to my Space Shooter template which I imagine may have been similar to your issue. (Not that I can say for sure, but it sounds it.)

If you cannot get it to work and cannot find an answer, I do offer paid support (separate from and not associated with Ansca) via my website, http://Techority.com.

Often I find the solution is just to test, change a little, test, change a little, etc.

However, timers frequently seem to fix this sort of issue :slight_smile:
