You need 2 things :

• the size of your array to be odd numbers
• your starting coordinate of the algo to be odd as well

So make the Array size 39,29

And event 3 replace the 2 first actions by:

System: set x to floor(random((Array.Width-1)/2))*2+1
System: set y to floor(random((Array.Height-1)/2))*2+1

do you want your particles to collide? or is it just a eyecandy fx ?

I did a tetris game some weeks ago, and to get the shape I simply wrote down some relative coordinates.

It looked like

-2,0|-1,0|0,0|1,0#0,-2|0,-1|0,0|0,1
0,0|1,0|0,-1|1,1
-1,0|0,0|1,0|0,-1#0,-1|0,0|0,1|1,0#-1,0|0,0|1,0|0,1#0,-1|0,0|0,1|-1,0
-1,0|0,0|0,-1|1,-1#-1,-1|-1,0|0,0|0,1
-1,-1|0,-1|0,0|1,0#0,1|0,0|1,0|1,-1
-1,0|0,0|1,0|1,1#0,1|0,0|0,-1|1,-1#-1,0|-1,1|0,1|1,1#-1,1|0,1|0,0|0,-1
-1,1|-1,0|0,0|1,0#1,1|0,1|0,0|0,-1#-1,1|0,1|1,1|1,0#0,1|0,0|0,-1|-1,-1

What would you want your particles to do ?

That's a weird question, so I'm interested.

What do you call "events of the same type"

And can you give us a practical game situation where it would be usefull.

Anyway I think GenkiGenga's solution is probably what you are looking for. But just to be sure.

Nothing wrong with your events.

It's just that... The Array object isn't in the layout.

(as a side note you don't need the TokenVar variable you can just use loopindex("Y")*3+loopindex("X") )

orcKilling.capx

really basic no animation just dumb sprites. (:

Ok I think I understand, you use the player_mask sprite so the feet only collides with walls, the player_collision is in fact a hitbox, and then the player is just the visual.

And you do the same for orcs.

That makes sens and I would probably do the same.

However, your capx is already too complex for me to make any changes. I prefer starting from scratch and show you the how to with it.

You'll probably understand better and be able to implement it in your own capx.

First, what is the use of the orc_mask ?

Second, shouldn't it be easier to name your animation "running_0" "running_45" "running_90" etc and just make one call like Set animation to "running_"&self.DIR ?

Third we'll see after you answered these question, but what you wana do is pretty doable

no you didn't understand my point so I think I'll make a capx 'cause we will run in circle.

Hop! familyOfEnemies.capx

Add a family variable called 'point' which hold the amount of point for each object in the family and then

Global number score = 0
ObjectA: On collision with family1
  -> System: add family1.point to score
  -> family1: destroy
