2D - "Entity System"

[backslider]

Hi guys,

would you be interested in a "2D Entity System" where you can easily create an entity like in the 3D Entity System and then use powerful functions to move / rotate them?

An example code with 10 boxes moving relative to there parents would look like this:

Code (glbasic) Select Expand


// --------------------------------- //
// Project: 2DEntity
// Start: Friday, June 15, 2012
// IDE Version: 10.202

SYSTEMPOINTER TRUE //enable the system pointer

//grab a test sprite
LOCAL spr% = GENSPRITE()
DRAWRECT 0,0,10,10,RGB(255,0,0)
GRABSPRITE spr,0,0,10,10

//---INIT ENTITY STUFF---
LOCAL es2D AS T2DEntitySystem //create a new entity system

LOCAL boxes[] //entity array

//create 10 entities in a line
FOR i%=0 TO 9
LOCAL box% = es2D.CreateEntity(i * 30, 0, 0)
es2D.SetTexture(box, spr)

IF i > 0 THEN es2D.SetParent(i, i-1) //the entity before is now the parent of this entity
DIMPUSH boxes[], box
NEXT

LOCAL angle# = .0

//---MAIN LOOP---
WHILE TRUE
LOCAL mx,my,b1,b2
MOUSESTATE mx,my,b1,b2

        //move the angle with the mouse buttons ;)
angle = 0
IF b1 THEN angle = 1
IF b2 THEN angle = -1

FOR i%=0 TO 9
es2D.Rotate(boxes[i], angle*i/10)
NEXT

es2D.SetPosition(boxes[0],mx-5,my-5)

es2D.DrawSystem() //draw the whole system with only one command :)
SHOWSCREEN
WEND


The result would look like the demo in the attachments :

Yeah, it would be very good for even manage game menus with transitions easily.

Is a great idea.

Maybe monday I will upload a first version of the system!
