Off-Screen Enemies

[BenMo]

I've been using Click products for a while, but I've never really figured out how to handle off-screen enemies in a smooth way. I've tried monster generators, and also the "Enemy Leaves the Frame" events, but neither seem to work.

What is the accepted method of creating a system where enemies appear when you reach a certain point in a stage, and don't follow you forever if you run away, but instead respawn if you come back later? Thanks!

If you have multiple spawn points: store the fixed value of the spwan point in an alterable value of the created enemy. If you want to set him back to his "home", you can use this to find the right spawn point.

Then you need to retrieve the distance between player and enemy. If the player is too far away, set him back home.

That works fantastically! Thanks!

However, I'm still having problems with my other post, the Block Pushing one a few posts below this one.

Well, it working fine for a little bit...I don't really need the enemies to go back to their spawn point when they leave the area, just be destroyed. Currently I set up the events...

WHILE:
- Distance between Player and SpawnEnemy is < 500
- SpawnEnemy's flag 0 is off
DO:
- Create enemy
- Set SpawnEnemy's Flag 0 on

WHILE:
- Distance between Player and SpawnEnemy is >= 500
DO:
- Set SpawnEnemy's Flag 0 off

However, this only works when there is one spawn point. If there are more than one, things start to get messy. If there are two onscreen at once, then they both spawn, but then never spawn again. And if there are two in the level but not onscreen at once, then neither of them ever spawn.

What can I do to make this simply work? Thanks again.

It could help to identify each spawn point more clearly. For example, spread value 1 in their alterable values.

Loop for the number of SpawnEnemy times:
If Alterable Value of SpawnEnemy=Loopindex (this picks one specific spawn point after another)
+ your other conditions

Sorry, but I'm having difficulty with the loops; I'm not familiar with them. Could you be more explicit in the events you recommend? I've added the

- If Alterable Value of SpawnEnemy=Loopindex
+ Distance from Player to SpawnEnemy < 500
+ SpawnEnemy flag is off

but I'm not sure where to start the loop or what else I need to do in order to complete it. Thank you for your time.

Basic principle of loops.
