More Collision Codes

Direct from Dan at 2Simple;

You can add code which will take effect when a monster collides with the player.  You can, however, use the code below to add collision code between any 2 objects of your choice. For example, drag the top sun to the canvas and add the following to the animation code of any object : 

if (_root.distBetween(_root.player,_root.s22) < _root.hitDist) { _root.player._xscale ++; _root.player._yscale ++; }

This means that whenever the player collides with the top sun, the player will increase in size. The function "distbetween" calculates the distance between the 2 objects that it is given. "hitDist" is one of the variables defined in the initial section of your code and defaults to 40. 

You could add collision code which checks for collisions against multiple objects - for example

for (n=22; n<=31; n++) {

ob = eval('_root.s' add n);

if (_root.distBetween(_root.player,ob) < _root.hitDist) { _root.player._xscale ++; _root.player._yscale ++; }

};

The above code checks whether the player has collided with any of the suns.

- Note - change "player" to "car" for the journey game.

- Note - for Collecting and Journey the top sun is s22. For Maze, Platform and Snake the top sun is s23. 

Repelling in a Journey activity

A while back I posted an activity (built from the "collecting" template) involving rounding up sheep. I didn't like how you could round up the sheep, but had to include another "apple" element - a clock to collect - to end the activity.

Playing around with the "journey" template I've discovered another neat trick. In the image below, I have set the "car" to be green square at the bottom of the screen (this doesn't move because I set the velocity to 0 in the start button script). 

• The blue square is your object to move - like a sheepdog - controlled using the Q, A, O and P keys. It is actually a monster element, with the collision action set to do nothing. 
• The red squares are monster elements to avoid (although at the moment they do not affect your blue square). 
• The yellow squares are "apple" elements that need to be guided to the green square by being repelled from the blue square as it moves using the repel code.

I can't think of a particular activity that would make use of this idea at the moment, but I'm sure one will come to me soon!
