Hi,

It has been a long time since I got the time to develop my game but here I am.

I am having difficulties to update from v1.2 to v1.3. I used the map upgrade from the editor but all my maps that contain entities will just crash the editor when loading and without getting any error. I checked further by trying to run them with the game executable. Here is what I get for one map (see attached)

I checked the dat file and got to the lines in question:
switch{
  layer = 0,
  x = 1544,
  y = 1608,
  name = "secret_chest1",
  subtype = "1",
  needs_block = false,
  inactivate_when_leaving = false,
}

The second argument is suppose to be the ground type if I understood correctly. In my map, it is the x position of the entity itself.

What should I do to change this and be compatible with v1.3?

Thank you!

Hi evrybody,

I just uploaded a video of a part of one of my dungeons. Not the best video ever recorded and have no sound but anyway, Enjoy!

By the way, does anybody have a good desktop recorder I could use, VLC does not want to record my speaker sound.

Hi,

I know you can save ground to reset the hero to a position when he falls but is it possible to do the same with lava and water?

Thank you!

Hi everybody,

I want to share some enemies that I have created with you. Could be useful for your projects. All of theses enemies are compatibles with this script http://forum.solarus-games.org/index.php/topic,51.0.html made by Christopho to reset enemies positions when crossing a separator.

I will add enemies time to time as I go in learning lua.

Homing bat
Simply, it is a bat that stands and do nothing. If you come close enough, it will go at you in a straight line. I used the Ganon firebat graphics for this, I changed the graphic script though to make it more realistic.

fire_bat.dat modified script:

Hi,

I was wondering if it is possible to reset the enemies position when changing region in a map, when crossing a separator.

What I actually do is put a sensor at the start of each region of the map and reset the not already killed enemies position of the region. Is there an easier way?

I do the same trick instead of using enemy:set_optimization_distance() to stop the enemies of next rooms.

Thank you!

Hi, I am trying to port my data from V1.1 to V1.2. I checked the porting guide but there is no mention of this problem.

When I start the game I get:
Fatal: Cannot load font from file 'text/fixed8.fon': Couldn't set font size

There is a fixed8.fon that exist in /text in my data folder after I updated the files with the V1.2 editor. I am not sure of what the problem means. Could it be simply that the engine is trying to find the file in ./text instead of ./data/text?

hank you for your help.

Best regards.
