Move Image in restricted field

[pradeepkrao]

Hi,

I have map and a player (I am reffering to bitblt game which i have posted earlier in this forum)

I want the user to be restricted from running over water etc etc.

Could anybody pop up some idea's.

Thanks,
Pradeep

Sorry I didn't watch your post but here's the theory:

In your map (or in the tiles) store a value Walkable (or Collision if you prefer) and when moving the player check the target position if it's allowed to walk there. If the player position is in pixel you have to divide it to get the map position, something like this:

If Tile( Map( player.x / 16, player.y / 16 ) ).Collision then
    'Reject movement
Endif

Btw: Thanks for remembering me, I'll write a tutorial about this when I'm done with the tiles one.

Fox,

I have made a tile game as you mentioned in yesterdays thread..

I am not loading the BMPs at runtime..

This is what i have done..

Create a Map using my own editor
and save it as a whole BMP also save a txt file with the tile numbers..


Map

+------+------+------+
| | | |
| 5 | 1 | 2 |
+------+------+------+
| | | |
| 3 | 6 | 5 |
+------+------+------+
| | | |
| 6 | 1 | 8 |
+------+------+------+

Txt file

5
1
2
3
6
5
6
1
8

Where the numbers corresponds to the tile numbers..

Now i load this file in my game and the background still
remains static.

I know the restrictions for my users and thus my game goes..

find it at

Here

I will read your tutorial now.. It looks very Good..

You're not suppose to save the map as a bitmap... and about saving the files, I'll update the site today and add another tutorial showing you how to save/load binary files. Well keep reading anyways, it shows you how to implement a virtual camera you can move around your map and even how to animate tiles.
