How to make an enemy appear randomly at locations?

[Fr34kSh0w]

Alright, basically I need a way to let an enemy appear randomly in set intervals at set locations. It should be as random as possible, thanks alot!

Put an invisible "spawn_point" object (ie. an active object) at each of the set locations, and then just say:

+ Every <whenever>
+ Pick one Spawn_Point at random
-> Create Enemy at 0,0 from Spawn_Point

Or easier:
* Every 1 second
-> Create enemy at -22, -55.
-> Enemy-> Set position to X: random(640)
-> Enemy-> Set position to Y: random(480)

I use MuddyMole's coding on my games. Grim...an enemy could find itself in a rock with your way, and there is more control for the coder the other way IMHO.

i use a technique similar to Muddy Mole,

i create an invisible active and change its coordinates to random x y, every 0.01 seconds

and create object @ location of active, whenever you want

Thanks alot to MuddyMole! You've helped me out, thank you very much!

It's not really hard to prevent this. You can simply use flags with my example. I used my system many times.

* Every 1 second
-> Create enemy at -22, -55.
-> Enemy-> Set position to X: random(640)
-> Enemy-> Set position to Y: random(480)

* Enemy-> Flag 0 is off
* Enemy-> Overlapping with rock, stone, wall, whatever
-> Enemy-> Set position to X: random(640)
-> Enemy-> Set position to Y: random(480)

* Enemy-> Flag 0 is off
* (negate) Enemy-> Overlapping with rock, stone, wall, whatever
-> Enemy-> Set flag 0 on

Or you can use better loops and give objects' IDs by spreading values, this would be the best way.

I use muddyHole's method, but i make the active a bouncing ball set at blazing speeds and with full randomness.

Well Grim, now your code is not simpler. There are many ways to do the same thing in MMF. If I may suggest, that we each pick what works best for us and go on helping other forum members.
