Make enemy follow Player?

sokaroka

I'm making a game similar to tilt to live on iPhone.

It's a survival game where you must avoid enemies that kill you when you touch them.

I need the enemies to move towards the Player.

Also can you make accelerate stop at a certain speed?
I want them to go towards the player at a speed of 100, not accelerate from 0 - 100, but just go at 100 the whole time.

Wrap up, how can I make the enemy move to the Player position at a set speed of 100?

Constrain the player's X and Y position to new attributes (integer) - PlayerX and PlayerY

On your enemies have the behaviour:
Move to Player X, Player Y

That should do it...

I figured this out for my game, It's pretty easy, if you want the enemies to rotate toward the player, you can use the behavior: Rotate to Position. And just set the X and Y to the playerX & playerY variables.

Sorry but how do I do that?

Do I use the expression editor?
I tried searching through that but found nothing...

Ok what I think I've done...
On the player I got a Constrain attribute, setting self.Position.X/Y to PlayerX and PlayerY.
Then on the enemy I have move to PlayerX, PlayerY.

But then enemy moves to 0, 0
Which is the players starting position, so I didn't think it was continuously updating.
I then put a timer, to make the enemy move to PlayerX, PlayerY every 0.1 seconds, but it still just went to 0, 0 and stopped.

Please explain for a noob

Also you said just set the X and Y to the players x and y variables...
How do I do that?
If I use the expression editor on the enemy, I can't find Player in the "game" directory...

make 2 game attributes

playersx and playersy both of them type real

the in your players do this

timer
every 2 seconds

change attribute game.playersx to self.position.x (or Constrain attribute)
and
change attribute game.playersy to self.position.y

then on your bullet do this

Take a look at my game Fireflight.

The homing missiles, people and boss droids use a timed fast Accelerate to behaviour balanced with a heavy Drag.

Sorry, need to feed the baby. I'll post a more detailed explanation tomorrow.
