Also do you guys know how to make a map horizontally infinite ? Both questions are for a shmup.

[Dr. Cooldude]

The movement of the Medusa Heads (assuming you're talking about Castlevania) seems to be a simple linear movement on the X axis (towards the player), and a sine wave movement on the Y axis.

I haven't used Game Maker for at least a billion years, but I found this tutorial on the internet: http://csanyk.com/rants/2012/10/game-maker-wave-motion-tutorial/ Thought it might help.

making the map horizontally infinite isn't the way you do this at all. what you do is simply check if the medusa head's x is beyond the room_width or less than 0. if so, move it to the other side of the map from where it is. you can make an object wrap around a map without making the map actually wrap around itself

as for the up and down movement, use sine waves; it's pretty simple, a lot of sine methods can work. something simple like y = ystart + 40*sin(x); works wonders. to get it to look the way you want you may need to adjust those values, like maybe y = ystart + 60*sin(x/3); would work better. adjusting the stuff inside the sin will change the frequency of the wave, and adjusting the value the sin is multiplied by will change the amplitude of the wave

Thanks, guys. It worked.
If a i wanna put the score in a math function, how do i do that?

[s0]

Score can be used like any other variable. For instance to add 50 to your score, use score += 50.

y = sin(a)*40;
a++;

holy crap sin where have you been all my life <3

Thanks for the traffic:) I'm glad you liked it.
