Looking for help

So I want these creatures to move towards food when it is in their vision, the food is inside of a table and randomly spawned.

Here is the code I used to move the creatures:

function moveCreatures(dt)
for index, creature in ipairs(creatures) do
dir = rand(1, creature.chanceToMove+4)
if dir == 1 and creature.x < gridXCount then
creature.x = creature.x + 1
creature.survive = creature.survive - creature.cost
elseif dir == 2 and creature.x > 2 then
creature.x = creature.x - 1
creature.survive = creature.survive - creature.cost
elseif dir == 3 and creature.y < gridYCount then
creature.y = creature.y + 1
creature.survive = creature.survive - creature.cost
elseif dir == 4 and creature.y > 1 then
creature.y = creature.y - 1
creature.survive = creature.survive - creature.cost
end
end
end

So what is not happening? What is going wrong?

In higher abstraction it looks like:

Code: Select all

function moveCreatures (creatures, dt)
	for index, creature in ipairs (creatures) do
		local direction = chooseDirection (creature)
		if canMoveInDirection (creature, direction, dt) then
			moveInDirection (creature, direction, dt)
			takeEnergy (creature, dt)
		end
	end
end

It looks like that you don't use the dt and the moving distance will be always 1.
