Here is the idea: A reaction time test for children for scientific research on an Android tablet. The children have to tap a button on certain events. The reaction time gets stored in a file (preferably a .txt or similar) which we can later transfer to a computer to evaluate the data.

I have no idea how to start... Should I store the data in variables and send the values to a file? And if so how do I manage to create such a file?

I've read some where that AJAX is the key here but because I have no experience with web coding I don't know how to do it.

but like I said it gets out of hand with the comparisons on loads of objects.

That's one major problem in our project.

Another problem we have to solve is that all our objects have different actions. In our case a tap on object A should trigger sound A and tap on object B should trigger sound B.

We can not apply a action to the family as a whole because of that.

In a scenario like the one below. How would I solve the problem?

On left mouse click resize the sprite.

The event sheet:

Layout:

If I click in between the objects both of them resize but I just want the green box to get bigger and not the pink one to get smaller.

Two sprites overlap each other. If I click on one of them sprite specific actions happen. Problem: If I click in an area where both sprites overlap the action of the bottom sprite is performed.

Possible solution: Create an array. All touched sprites will be listed in one column and their layer in another column. Now sort the list by layer and choose the object with the highest layer. Now perform just the actions for that object.

Are there any better solutions? If no, how would I create such an event in CS2?
