Increase speed

[Rabagast]

Hi!
I have an enemy I want to increase the speed with 5 every 30 sec. What is the best way to do that?

[alspal]

Use the timer object and do every 30 seconds then for the action, go to set speed for the object. Then type: Speed( "enemy" ) + 5

If you're creating and destroying enemies, you might want a slightly more robust approach:


+Always
=Set Speed of "Enemy" to 50 + seconds / 6

or
50 + int(seconds / 30) * 5

Thanks to both of you. I will try it later.

alspal's example works great, but when I destroy the enemy and it creates a new one, the speed is starting at the beginning.

I tried Pixelthief's example too, but I can't get it working.
Can you please give me a little more detailed?

whoops I made an error on that
hah, I always mix that up


I forgot, "seconds" returns only the seconds part of the timer, which keeps resetting from 0 to 59. Theres no built in function to return the # of seconds since the game started.


Change it to say



+Always
=Set Speed to 50 + int(Timer / 30000) * 5


Timer gives it in 1/1000 seconds (milliseconds) since the start of the frame. So 30000 millseconds = 30 seconds. The "Int()" function will round this down, so it will always jump up from 0 to 1 to 2 to 3, where if you didn't use int() it would take fractions like 1.24 and 3.45 seconds, and the speed would be moving up constantly instead of +5 every 30 seconds

I must do something wrong, Because it doesn't seem to work. The enemy is moving the speed of 50. I change 50 with 12 and the enemy is moving slower, but the speed doesn't change with 5 every 30 sec.

Heres an example file:
(using 10 base speed and +10 speed every 5 seconds)

Thank you.

I have another question. After I have killed the last enemy, I want to create one more enemy. Example:

In start of frame, I have 1 enemy. I kill it and 2 more enemies is appearing. I kill these two. 3 more enemies is appearing, etc, etc.

I have tried with loops, but without luck. Can anyone help me?

Thanks
