Well, if the direction is changing by 1 pixel each step, that should give it a 360 pixel circumference, or about a 115 pixel diameter, or even further, about a 57 pixel radius. If you would like to have each platform a fixed distance away from a point, i suggest using variables that can be differentiated in the creation code. EG: [code]x += xspeed; y += yspeed; dir += 1; xspeed = lengthdir_x(increment, dir); yspeed = lengthdir_y(increment, dir);[/code] If you want to avoid doing a bunch of math to find out the distance, putting this in the creation code in the room should work: [code]local.distance=xxxxxxx local.circumference=local.distance*2*pi increment=(local.circumference/360)[/code] substitue "xxxxxxx" with the distance away from the point

I need help.I tried to make goomba(obj) learned from Catezeey's OSMB engine(DE7 is somehow complicated for me) ,I add new objs for it but when i test it didn't get stomp,it just hurted me.Did I miss anything?

You may want to check where the sprite's y origin is at. If it is a 32 pixel tall sprite and the origin is at 16, then that wont work. If it is at 16 and the sprite is 32 pixels tall, for example, this code would work better: [code]if other.y < y-15+other.vspeed { sound_play(snd_stomp) instance_create(x,y,obj_stomped) with (other) event_user(1); instance_destroy() }[/code] And for the goomba not hurting Mario. I don't know why its there, but its checking to see if mario's y coordinate is greater than the goomba's y coordinate minus four. This would only be possible if the sprites y origin would be around 16 pixels from the bottom

Tks.But when I stomped on it hurted me.

I need help with platforms that move on a line. The platform has gravity but it moves on a line until the line ends and it falls or something like NSMBWii. I also need this to work with touch to move platforms. I am talking about those line paths that you place for platforms to move. The code should work with objects like coins or fuzzies.

Try using paths.

Well paths can get confusing after a while because I have to make a path for every object on the line. If they all use the same path they will go out of the line.

Ok. Use creation codes like this: [code]varpath = path0[/code] And add this to create event: [code]alarm[0] = 1[/code] And add this to alarm 0: [code]path_start(varpath,2,blah,blah)[/code] This makes using paths easier. [size=50]Also why I didn't using this?[/size]

I have a problem with weird acting sprites in my game. When the player moves against the wall (you can't move him by pressing left and right btw, he moves automatically), and goes to the left, the sprite sort of 'flashes', I don't know how to explain. But normally, move_snap(1,1) would fix it, but now it doesn't for some reason. (To explain the problem better: it looks like his x just changes by 0.1 pixels to the right, so it 'flashes', the far right pixel gets small, big, small, big etc.) Here's some additional information: Hspeed: 0.5 Room speed: 60 When it touches a wall, it changes direction and moves 1 pixel the opposite way. Hope someone can help me out.

I can almost guarantee that that is visible on some computers and not on others. Try moving the move_snap thing to end-step, or when drawing, round the place where the sprite is drawn. That might make it snappy-looking, though...

Moving it to end-step would let the player stop moving, though, because the hspeed is 0.5 (I used alarms), and the sprite isn't been drawed. Thanks for your help, though.

Thanks for your help, though.[/quote] well since a sprite can't be drawn on a half a pixel you could do something simple like this in the draw step and you won't have those nasty half pixel graphic glitches: draw_sprite_ext(sprite_index,image_index,floor(x),floor(y),image_xscale,image_yscale,image_angle,image_blend,image_alpha);

Only problem is it may look snappy at some speeds (though probably not 0.5 so I reckon you're good with that).

I already fixed it by changing the room speed. Thanks for helping, though.
