choose(val0, val1, val2... max_val);
| Argument | Description |
|---|---|
| val0... max_val | An input value that can be string, integer, variable or constant. |
Returns: One of the given arguments.
Sometimes you want to specify something other than numbers for a
random selection, or the numbers you want are not in any real order
or within any set range. In these cases you would use
choose() to generate a random result. For example, say you
want to create an object with a random sprite at the start, then
you could use this function to set the sprite index to one of a set
of sprites. Note that you can have as many as you require (more
arguments will mean that the function will be slower to parse).
NOTE: This function will return the same value every time
the game is run afresh due to the fact that GameMaker: Studio
generates the same initial random seed every time to make debugging
code a far easier task. To avoid this behaviour use randomize at the start of your
game.
sprite_index = choose(spr_Cactus, spr_Flower,
spr_Tree, spr_Shrub);
hp = choose(5, 8, 15, 32, 40); name = choose("John", "Steven",
"Graham", "Jack", "Emily", "Tina", "Jill", "Helen");
The above code uses choose to set a number of properties for the instance.
