[Game] Bulldozer

05 Jun 2018, 09:42

Introduction
Bulldozer, developed for AutoHotkey by Weston Campbell (TheDewd), is a recreation of the original Bulldozer game series created by John 'FlyMan' Hattan (The Code Zone).

Bulldozer 1 first appeared in 1994 on the CD-ROM game compilation "24 Games for Windows 95" developed by The Code Zone for Expert Software, Inc. Bulldozer 2 became available in 2000 on "Arcade Magic", also developed for Expert Software, Inc. Bulldozer 1 & Bulldozer 2 were re-released in 2003 on "Blazing Games", a compilation of fifty games developed for Cosmi Europe, Ltd. Bulldozer 3 was completed in 2002, but remained unavailable until the 2008 release of Bulldozer which included all 180 levels from the Bulldozer trilogy. The 2008 version was created using Adobe Flash and is available on a variety of desktop and mobile platforms. Bulldozer is a variation of the popular Sokoban puzzle game.

All credit goes to John Hattan for the original idea of the Bulldozer game series. This project was an exercise in GDI+ and string manipulation, and is intended to pay tribute to the game I played in my youth.


NOTE: The game script has changed drastically since it's earliest releases. Many of the replies to this post may be referencing an earlier build of the game or features that no longer exist. I apologize for any confusion that may occur if you read the earlier replies.

Game Objective
The object of Bulldozer is to push each rock on to a target.



Movement
Move the bulldozer using the arrow keys, or WASD keys, on your keyboard. The bulldozer can move horizontally and vertically.

Image

The bulldozer will not move if one of the following three conditions are true:

(1) You are trying to push multiple rocks...

Image

You can only push one rock at a time!

(2) You are pushing against a wall...

Image

The bulldozer can't move through walls.

(3) You are pushing a rock against a wall...

Image

Be careful about pushing rocks against walls. The rock might become stuck, and you'll be forced to restart the level.

Image

However, it may still be possible to reach the target depending on its position.

Image



Completing a Level
Progress to the next level by moving all of the rocks on to the targets. Each level will have the same number of rocks as targets.



Hints
Carefully plan your moves. It's easy to get stuck which may force you to restart the level.

A rock is not locked into position once it is placed on a target.

- Game looks phenomenal cheers. The 2 things to mention are that it flashes black each time you move, and that you can't hold down the arrow keys, you have to press repeatedly. But all of the key stuff is done, cheers again.

You're correct! The issue only occurs for me when using the classic Windows interface. On Windows 7/Windows 10 using themed interface the issue is non-existent. I'm currently implementing a working solution to this for the next update by using BitBlt.

I disabled the repeat initially to allow the script time to fully update the background image and other things so that the player doesn't notice the "lag" between updates.

I have yet to completely read the entire source but it looks promising.
You should probably rather draw an entire picture and display the whole game as one picture instead of using seperate picture controls.

There is a "Level Select" menu item in the "Game" menu in the menubar, or press F3. Enter the password to load a specific level.

OK that makes sense :)

Good job on the game. Level 6 took me about 6-8 tries. The rest were pretty easy except I lost my motivation at level 10 :) Now I wish I had noted the password for that level.

Just one more: "Impressive, thanks for sharing!"

Your script doesn't run on AHK Basic. So you don't need those (A_PtrSize ? "UPtr" : "UInt"). You can safely use "UPtr" or "UPtr*/"UPtrP".

Some thoughts on BackgroundLoad():
  • As far as i can see the tile images will never be changed. So you need to load them into pTilemap only once when the script starts or the tile map will be changed (e.g. in OnLoad()) and destroy the current tile map in OnUnload().
  • Also, you can reuse the GDIP background image and its graphics. They also can be created in OnLoad() and destroyed in OnUnload(). (This would even allow to update only the tiles of interest, 3 at most.)
  • Code: Select all

    	; Create brush
    	DllCall("Gdiplus.dll\GdipCreateSolidFill", "UInt", 0XFF808000, (A_PtrSize ? "UPtr*" : "UInt*"), pBrush)
    	; Fill bitmap graphic with brush color
    	DllCall("Gdiplus.dll\GdipFillRectangle", (A_PtrSize ? "UPtr" : "UInt"), G, (A_PtrSize ? "UPtr" : "UInt"), pBrush, "Float", 0, "Float", 0, "Float", 640, "Float", 384)
    	; Delete brush
    	DllCall("Gdiplus.dll\GdipDeleteBrush", (A_PtrSize ? "UPtr" : "UInt"), pBrush)
    
    might be replaced by

    Code: Select all

       DllCall("Gdiplus.dll\GdipGraphicsClear", "Ptr", G, "UInt", 0XFF808000)

Nice script, thanks for sharing :D

The level-select password system seems to be not working here. Rev 3. Windows 8.1 Single Language (64 bits).

Revision 4 (2018-06-11)
  • Added levels from Bulldozer 2 and Bulldozer 3
  • Resized level area for compatibility with maps from Bulldozer 2/Bulldozer 3
  • Optimized level drawing to update changed tiles only
  • Redesigned 'Level Select' and 'About' menu item contents
Note: The passwords are different from the previous versions due to changing the formatting of the level data for compatibility with the larger maps added for levels 61-180. I apologize for any inconvenience.

I hope you all enjoy the game!

:bravo: Wow, what a difference! It's really smooth, no flickering, repeat works great.
Those changes in BackgroundLoad(MapData) worked wonders.
Thanks for sharing this.

Great, great, great! Very smooth, some constellations are really not too easy!

P.s.: Level 24, wall seems to be rock (not bulldozer alone) permeable at least at coordinats 2,4; 3,6; 4,5; 4,7; where 0,0; being upper left corner.
