Short and Simple Map System

Target: GM6/7

Creating a map system is not as insanely complicated as you might think it is. With a few global variables, you too can create a SMB3 clone...

First off, on the Map Screen, we have our Mario. Here's how he works. When we push a key, he jumps 16 pixels in that direction; it helps if his collision mask is only 16x16 as well.

Now, for the room, make sure it's persistent! If it isn't, you may have a few problems. So in the room settings, make sure Persistent is checked.

But how do we stop him from going in that direction if there's a block? Well, here's the same event, but with the code that prevents this;

There. Now just place a solid object in the way and he won't move.

Now, to create a level, just make an object, and when the player hits a certain key, we use the level object's key event. Here's an example with the Shift Key...

This sends Mario to the level.

Now, when Mario clears the level, make sure that in the event, you set this variable.

Then, when you return to the map, this will be in the Map Mario's step event.

In obj_map_clearer, we make the collision event with the blocks that impede progress DELETE these blocks.

Also, make sure obj_map_clearer deletes itself after a little while. That you can figure out easily, can't you?

And voila; a short, simple, dirty map system. Enjoy.

I happened to come across this, and felt that it belonged here.

replace "character" with the name of the main character object (Mario, Yoshi etc...).

IMPORTANT: ONEWAY PLATFORM OBJECT MUST NOT BE SOLID

To character's Step event:

I havent been able to make this work (

Elite Charizard requested this, I decided to make it. This code lets you teleport a player somewhere without having the background position change.
To use, make a script named "teleport_with_bg".
Then add this code:

Run it as in: teleport_with_bg(new_x_position, background_index);

Sorry for The Bump.
Here Are Some Tutorials I made a time ago.(GM6 ALL)
All Links take to file directly, no need to go to any page and click more...except the huge mario source, didn't want to upload that on my site >.<
Goomba Tutorial:
Here:Download
Info:A Simple A.I Tutorial of How to Make a Goomba.Walks by Itself, Bounce(Change Direction) on Walls.
HUD Tutorial:
Here:Download
Info:Shows How To Make a HUD with Animated Helath-Bar Has a Score System, Life Counter and Bomb Counter.
The Bomb Counter Was a Copy of the Life Counter, to Show How To Create New Counters.
It Has a Limitation, For Example You Can't Get Passed 99 Lives or 99 Bombs, When The Score Gets to 100000 You Get An Extra Life and it Sets The SCore Back to 0.
Anything Can Be Fixed, Press Space To Test(It Adds One To The Lives/Bombs One Less To The Health and Score +100)
Mario Source:
Here:Download
Info:A Unfinished Engine I was Working On.
Warning:Slopes Are Pretty Buggy Because I Stopped Working On This After I Added The Slopes.
It Contains SMB3 Features such as Mario with Most of his Power-ups:Raccoon,Hammer,Fire,Small,Normal and I'm sure there is one More.
Lot's of Enemies A.I:Goomba,Koopa,Lakitu and More.
Map system with Many Features from the SMW Map System such as climbing swimming and Menu with Resume/Save/Load/Exit Options.
Remember Slopes where the last thing I added and never Finished therefor if I remember correctly only Mario and the Goombas can walk on slopes, Mario can butt-slide on Slopes.

Sound channels for fun and profit, "dumb" method - mmf2 can handle up to 32 sounds playing at once, however it can only automatically do this with internal sound files; use this if you need to use external sound files
Target Applications:

To start off, we need to assume two things:
1. You have a global/alterable string named "NextSound"
2. You have all of your sounds in one folder, in this case i'll use ".\Sounds", with sound files "Sound1.ogg", "Sound2.ogg", "Sound3.ogg" (use .wav files instead of .ogg if you have TGF2)

alternatively, you could use fast function and pass the sounds' names as an argument/parameter

i call this the "dumb" method because if, by chance, all of the channels are occupied, it'll just ignore the new sound's "request" to be played. one way to remedy this is to add an extra loop (so if you wanted to have 32 sounds, you'd run 33 loops), and if it manages to make it to that loop (only possible if all channels are taken), have it pick a random number from 1 to 32 and play the new sound over an old one:

Sound channels for fun and profit, "smarter" method

Two GM6 Examples.

Game Maker 6 Thwomp

Alarm Event for alarm 0:

Step Event:

Collision Event with object block:

This pretty much the minimal amount of programming needed to do a perfectly working Thwomp.

Also, keep in mind that these speed and alarm values are pended to fit 60 fps games.

replace "character" with the name of the main character object (Mario, Yoshi etc...).

IMPORTANT: ONEWAY PLATFORM OBJECT MUST NOT BE SOLID

To character's Step event:

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

COMPILATION ERROR in code action
Error in code at line 103:
If there is a collision with obj_onewayplatform (0,1)

at position 31: Unknown function or script: obj_onewayplatform

Ultramario, I can't get the oneway platform to work, what should I do?

This isn't written in GML you have to translate it.

Delagging HyperCam2 Videos:
Here a few few things you can do to reduce Lag in HyperCam2 Videos:
1: Go to Display Properties, Settings, Advanced, Trouble Shoot, and Drag the Slider to 3/5. It should say "Disable all cursor and advanced drawing accelerations. Use this setting to correct drawing problems."

2: Go to Display Properties, Settings, and set Color Quality to Medium/16-Bit.

3: Make HyperCam2 Film a Smaller Portion of the Window.

4: Make HyperCam2 Film at 30FPS, and have the Keyframe at 30FPS.

5: Make Cursor/Full Frame Capture Ratio higher, although this will Lag the Video, but Delag the Game.

6: Don't record Sound.

7: Set the Video Compressor to Full Frames (Uncompressed).

I use Options 1, 3, 4, and 6, and it runs for the most part Lag Free! And I use some of the most Ancient RAM available! DDR PC3200 RAM! O_O

EDIT: Oops, wrong thread, I'll move it soon.
