Module: PseudoGame.graphics.PolygonCollection

Class for storing multiple polygons in an efficient manner

Functions

PseudoGame.graphics.PolygonCollection:new ()	the constructor for a polygon collection
PseudoGame.graphics.PolygonCollection:add (polygon)	add a polygon to the collection
PseudoGame.graphics.PolygonCollection:resize (size)	make the collection be a certain size by deleting polygons if it's too big and creating new ones if it's too small
PseudoGame.graphics.PolygonCollection:remove (index)	remove a polygon from the collection (this does not shift other indices)
PseudoGame.graphics.PolygonCollection:get (index)	get a polygon from the collection
PseudoGame.graphics.PolygonCollection:copy_add (polygon_collection)	add the polygons from another collection to this one by copying them (uses Polygon:copy so this function is bad for performance)
PseudoGame.graphics.PolygonCollection:ref_add (polygon_collection)	add the polygons from another collection to this one by referencing them
PseudoGame.graphics.PolygonCollection:iter ()	an iterator to loop over all polygons in the collection
PseudoGame.graphics.PolygonCollection:generator ()	recreate all polygons in the collection while reusing the old ones (avoids table allocation so this is very good for performance)
PseudoGame.graphics.PolygonCollection:transform (transform_func)	transform the vertices and vertex colors of all polygons in the collection
PseudoGame.graphics.PolygonCollection:clear ()	clear all polygons from this collection (does not delete the items in the table internally, so it's fine performance wise to frequently clear a collection)

Fields

pseudogame.graphics.polygoncollection.size

Functions

🔗 PseudoGame.graphics.PolygonCollection:new ()

the constructor for a polygon collection

Returns:

PolygonCollection the newly created polygon collection

🔗 PseudoGame.graphics.PolygonCollection:add (polygon)

add a polygon to the collection

Parameters:

Name		Type(s)	Description
polygon		Polygon	the polygon to add

Returns:

number the index of the polygon in the collection

🔗 PseudoGame.graphics.PolygonCollection:resize (size)

make the collection be a certain size by deleting polygons if it's too big and creating new ones if it's too small

Parameters:

Name		Type(s)	Description
size		number	the amount of polygons that will be in the collection

🔗 PseudoGame.graphics.PolygonCollection:remove (index)

remove a polygon from the collection (this does not shift other indices)

Parameters:

Name		Type(s)	Description
index		number	the index of the polygon that should be deleted

🔗 PseudoGame.graphics.PolygonCollection:get (index)

get a polygon from the collection

Parameters:

Name		Type(s)	Description
index		number	the index of the polygon in the collection

Returns:

Polygon the polygon at the index in the collection

🔗 PseudoGame.graphics.PolygonCollection:copy_add (polygon_collection)

add the polygons from another collection to this one by copying them (uses Polygon:copy so this function is bad for performance)

Parameters:

Name		Type(s)	Description
polygon_collection		PolygonCollection	the collection with the polygons that should be added

🔗 PseudoGame.graphics.PolygonCollection:ref_add (polygon_collection)

add the polygons from another collection to this one by referencing them

Parameters:

Name		Type(s)	Description
polygon_collection		PolygonCollection	the collection with the polygons that should be added

🔗 PseudoGame.graphics.PolygonCollection:iter ()

an iterator to loop over all polygons in the collection

Usage:

for polygon in mypolygoncollection:iter() do
    ...
end

🔗 PseudoGame.graphics.PolygonCollection:generator ()

recreate all polygons in the collection while reusing the old ones (avoids table allocation so this is very good for performance)

Usage:

local gen = polygon_collection:generator()
for i=1,100 do
    local polygon = gen()
    -- since it reuses old polygons and creates new empty ones if there is none
    -- we don't know what vertex count the polygon has, so it makes sense to set it
    -- setting it to the number you need directly instead of setting it to 0 and adding
    -- vertices is better for performance (less (or no when reusing) memory allocation)
    -- (this is not required if you call methods like polygon:copy_data)
    polygon:resize(4)
    ...
end

🔗 PseudoGame.graphics.PolygonCollection:transform (transform_func)

transform the vertices and vertex colors of all polygons in the collection

Parameters:

Name		Type(s)	Description
transform_func		function	a function that takes x, y, r, g, b, a and returns x, y, r, g, b, a

🔗 PseudoGame.graphics.PolygonCollection:clear ()

clear all polygons from this collection (does not delete the items in the table internally, so it's fine performance wise to frequently clear a collection)

Fields

🔗 pseudogame.graphics.polygoncollection.size

Name		Type(s)	Description
size		number	the amount of polygons in the collection
