Scrolling tile maps with Hollywood

[jalih]

Hi all,

I added a function to render scrolling tile maps into my framework.

I made a simple demo to show off it's functionality. I was lazy, so random map is generated. Could you test it with AmigaOS4 and MorphOS? Please give me information on how it performs and if you find any bugs.

Demo available here.

I will try to get my AmigaOS4 machine running again in near future, so I can use the latest version of the Hollywood. I wonder, if support for hardware brushes would help performance...

Hi,
here on a Powerbook G4/1.67GHz under MorphOS I have around 14-16 fps.
No bugs encountered.

Tried it... the tiles are currently all messed up and do not show any level layout but I think that's intended. Concerning speed, I'd say that hardware brushes and a hardware double buffer should really speed things up here significantly.

Yep, the demo just creates the map using:

Code: Select all

dim map[20][20]

For Local row = 0 To 20-1
  For Local col = 0 To 20-1
    map[row][col] = Point:new( { x = Rnd(7) + 1, y = Rnd(5) } )
  Next
Next

The map tile graphics are all saved in one image and the tile map engine knows which one to draw based on the id number.

We just need to define the tile rectangle, map rectangle, view port rectangle and position offset point for the view port rectangle.

To draw the tile map, we call the drawing function with the above information and with our position on the tile map. That's all what is needed...

Code: Select all

game.buffer:drawtilemap(map, mapr, tiler, vpr, vprpos, pos)

I updated the package, please test.

- Added support for the hardware double buffer and hardware brushes

Tried it, it's clearly faster than the old version. Maybe about 6 fps faster here on Pegasos 2.

Demo download updated to show the current capability.

I can now also support collision rectangles on maps.

Here is a Windows binary for the demo of the current status of my tilemap engine.

- Uses three tile sets
- Uses three maps layered to look as one.
- Uses separate view ports for each map.

Here is a demo for Windows showing the current status of my support routines for scrolling tile based games.

Sorry, ground collisions only now, the platform collisions will follow later. Uses real layered tile map with collision detection done using collision rectangles and collision points. Collision maps could easily be supported also.

Have fun!
