Are you one of those people who can't make those awesome explosion things that show up when enemies pop into the screen? Do you want them to simply make a smooth appearance? Well continue reading then!

1. In the create event, stick in a variable named "alpha" or something. Also make a variable named event or something. These two should be equal to 0.

Code: [Select]

alpha=0 //Set the alpha
event=0 //Event of Alpha

2. If you understood that, go into the step event. This code could help you out.

Code: [Select]

//Smooth Fading Transition
image_alpha=fade //This is the most important part! Don't remove it!
if event=0 {if alpha<1 {alpha+=0.05;} else {event=1}}
if event=1 {if alpha>0 {alpha-=0.05;} else {event=0}}

//Note: At the end of Event=1, you can change the "else {event=0}" to anything you want.
//You'll need to keep else in the code though, or else it messes up.

Yeah, I know it's nothing big, but I think it's better than popping in from nowhere and disappearing right away too. It works nice for some sparks.

Did you ever want to draw a spinning target to the mouse position? It's pretty much a simple code! However, I have found different methods for this.

Method 1: If you want the mouse x and y to meet at a location first, you can use the draw feature.

Code: [Select]

//Draw Event

draw_sprite(mouse_x,mouse_y,spr_MouseCursor)

You can do whatever. If you have registered or pro, you can expand that option to this one.

Code: [Select]

//Draw Event (For Pro or GM6.1 Registered)

draw_sprite_ext(spr_MouseCursor,image_index,mouse_x,mouse_y,1,1,0,c_white,image_alpha)

Now once you prepare your cursor, you'll need to setup the x and y collisions or something.

Code: [Select]

//Step Event!

if mouse_x=50 && mouse_y=25 {action=true}

Yeah, you'll have to edit that. Change the number, and the action=true part.

Method 2: I personally find this way to be easier. There's two options for the animated cursor then. One is to KEEP the image plain (for Pro/Registered) or the alternate way is to use Game Maker's sprite rotation feature in the sprite editor.

Alt 1: In the cursor object, setup the sprite. In the step event, add this code.

Code: [Select]

//Step Event (Pro/Registered Only!)
image_angle+=18 //You can change the number

Once you finish with that, you're set to go. Just make a collision event to indicate whatever.

Alt 2: In the sprite editor, make a copy of the sprite just incase you need the original. In your sprite, make a rotation by going to Animation>Rotation>whichever direction you desire. After that, you can just save that sprite and load it up into your object, no real code needed.
