[SOLVED]Update and remove object layers

[AdrianN]

Hi all.
Recently I have to make a 2d shooter (top down), in the game exist objects when I fired they are removed, like box (are object layers) and they have hp counter, but I have the problem to I can't delete or update the object layers
I used sti library to load the map
(box object layer, caja in spanish)
box.hp=100 -- exists
box.hp=box.hp-bullet.damage()-- collision
box.hp=0 -- remove

I tried to looking function in STI documentation, but nothing does work or only remove tile layer.

Edit:I used this code, looking in the forum and work for me, the sprite change

Code: Select all

for i, instance in ipairs(self.map.tileInstances[129]) do
      instance.batch:set(instance.id, self.map.tiles[265].quad, instance.x, instance.y)
end

But the collision still in the map, how I can change the properties (change collidable true to false).
I thinking to use the bump collision and change or is possible in sti (any function)
...anyone?

Code: Select all

for i=1,len do
	if collisions[i].other.name=="caja" then
		print(tostring(collisions[i].other.collidable))
		collisions[i].other.collidable=false
	end
end

like this code
