game - how can I drag objects (cars with numbers) into targets (start line) AS3.0.?

Question

I am having this problem, where I have several cars, numbers and letters, and need to put 5 cars in the starting places. -random order is ok.

I' having trouble finding in AS3 a way so that the EndX and EndY of each object can be in the starting lines and be considered right no matter the order!

I'm having trouble putting the code here so, heres a titanpad with the code:

this is the code: being (um, dois, tres, quatro) the movieclip instance name for each numbered car. https://titanpad.com/42vtnCbvLu

Answer 1

First of all, you could probably benefit by using the distance between two points formula and seeing if the distance is less than a certain value rather than checking in all 4 directions manually:

Math.abs(Math.sqrt((x2-x1)^2 + (y2-y1)^2))

Let the position of the car be (x1,y1) and the start position (x2,y2). This formula will give you the distance between the two points in any direction, and you could test maybe whether this value is less than your offset.

As for the cars in any order part, I'm interpreting that you have your cars and you want the user to drag them to one of 5 spots, a bit like this:

spot1

spot2

spot3

spot4

spot5

All with respective coordinates. My suggestion would be to have a boolean flag for whether each spot is occupied that stops the program checking whether a car is put there after it has been taken once. Once all these flags are true, then you can proceed.

Hope this helps.
