Game Maker Questions Topic!!!

[agentms11]

Hey, I've recently been helping a couple of people with their questions on Game Maker.
So I decided to make a topic.
Anyone with a question can ask here, and will be answered by MEEEEEE!!!!
Or by anyone else who knows the answer and ninjas me.
In other word, If you know the answer to someone else's question, you can answer.
Bear in mind, I'm not guaranteeing I'll be able to answer.
I'll try my best.

Here are some things I helped with so far:

I don't know how to make something light up when the mouse touches it.

Make 2 subimages (one dark and one light). In the "Create" event:

Code: Select all

image_index = 0; //this is which subimage it is showing (subimage 0 is the darker one.).
Image_speed = 0; //this is what speed the animation is playing at (in this case, 0, so it doesnt play.)

In the "Mouse Enter" event:

Code: Select all

image_index = 1; //It should show the lighter one.)
image_speed = 0;

In the "Mouse Leave" event:

Code: Select all

image_index = 0; //back to the darker subimage
image_speed = 0;

If you want to do this in D&D (Drag and Drop):In "Control", on bottom where is says "Variables", use the first D&D action ("Set Variable" (a gray square that says "VAR")).

I don't know how to make a "yes/no" message pop-up.

In the event that you want the message to pop up

Code: Select all

question = show_question( "Do you want to do something?" );
if question = 1
{
do something;
}

If you want to do this in D&D: In "Control", on top where is says "Questions", use the sixth D&D action ("Check Question" (a blue octagon that has a speech bubble with a question mark in it(put the actions that you want to happen if the player hits yes after it)).

I don't know how to make you restart the game when a block touches the mouse.

I had an object "mouse". In that object, in the step event

Code: Select all

x = mouse_x;
y = mouse_y;

If you want to do this in D&D: In "Move", in the middle where is says "Jump", use the first D&D action (Jump to position (a gray square that has 2 X's with an arrow pointing from one to the other)).
That is how to replace the mouse by the way (and in "Global Game Settings" make sure that the option "Display the cursor" is not checked).
Then in the collision event with an enemy

Code: Select all

room_restart();

If you want to do this in D&D: In "Main2", near the bottom where is says "Main", use the first D&D action ("Restart Game" (a gray square that has 2 arrows in a circle pointing at each other))
Its that simple...

how do you make it where a message will appear and it will have different options on it and it does different things depending on which option you selec

Code: Select all

message = show_message_ext( "What do you want to say?" , "Hi" , "Hello" , "Bye");
if message = 1
{
Do something;
}
else if message = 2
{
Do another something;
}
else if message = 3
{
Do something different;
}

EXPLANATION!!!

message = show message_ext( "What do you want to say?" , "Hi" , "Hello" , "Bye")

"message" is the variable. "show_message_ext" is the function.
""What do you want to say?"" is what the message box will show (the question).
""Hi"" is what the first button will say. ""Hello"" is what the second button will say. ""Bye"" is what the third button will say.
---

if message = 1
{
Do something;
}

If the variable "message" is equal to one (i.e. you chose the first button), then do something.
---

if message = 2
{
Do another something;
}

If the variable "message" is equal to two (i.e. you chose the second button), then do another something.
---

if message = 3
{
Do something different;
}

If the variable "message" is equal to three (i.e. you chose the first button), then do something different.
---

Oh, change the "Do something" with what you want to happen if the player hits that button.

tl;dr version: I helped with a few things.

I hope this topic lives...
(I doubt it though. I never havee good luck with topics)

Ok...

Questions:

I'm trying to figure out how to make the missles home-in on Super Sonic.

[agentms11]

I'm assuming you want it in D&D:
Just put this in the step event.

(On the first page ("move") on bottom)
x: sonic.x
y: sonic.y
speed: 5
stop at: solid only

Replace "sonic" with the object you want it to home in on.

Hope this helps!!!!!

How do you create sprite and object folders?

[Zed98]

I keep getting this:

Code: Select all

___________________________________________
ERROR in
action number 1
of  Step Event
for object Missle:

Error in expression:supersonic.x
 position 1: Unknown variable supersonic


[Suyo]

How is the object called? Is it supersonic?

[Zed98]

Name: Super Sonic

[agentms11]

How do you create sprite and object folders?

Right click > Create Group
OR
<Shift> + <Insert>

Name: Super Sonic

Don't put spaces in names.
Use "_" instead.
And it's case sensitive.
So if your object is called Super_Sonic you would have to do Super_Sonic.x
Hope this helps!!!!!

I now get this:

Code: Select all

___________________________________________
ERROR in
action number 1
of  Step Event
for object Missle:

Error in expression:Super_Sonic.x
 position 13: Unknown variable x

___________________________________________
ERROR in

for object Missle:

Error in expression:Super_Sonic.y
 position 13: Unknown variable y
