I see.. thanks for the advice Dop..

I am still learning all about this optimizing stuff especially what is the proper way to load the image file in game.. which one should be sprite, which one should be tilemap or tiledbackground when it come to be huge and a lot of images

I see.. thanks Dop..

other question :

So If Solid behavior need to apply in that Tilemap / TileBackground / Sprite, which one better ?

Well if I use Physics object for the player/enemies sprite, then I also need to apply Physics to all of those and set "immoveable" to tilemap/tiledbackground/sprite which hold the enemy to prevent it fall out from viewport

Object with solid behavior can hold the Platformer object,

but If Platformer change to physics, solid behavior cannot hold it.. should apply physic with checked immoveable

Is there any other trick to make less physics object ?

Or every object that physics immovable optionchecked consider as not physics object ?

I am sure it is there... Could you show your event condition ?

Maybe something in you event that prevent this action ?

Here what I do with Button Clicked event, and I can choose action System > Set Layout Scale

Which one should I use Sprite or TiledBackground or Tilemap ?

If :

Player Character = Sprite with animation, Platformer

Enemy Character = Sprite with animation, Platformer

1. If the solid area see picture below with red rectangle mark, also contain tilt area. Should I use a saparate hidden sprite (solid behavior) for the all the collision area, and leave all background design origin without solid behavior ?

2. Is it wise to use Tilemap to draw the background in this case, tilemap collision area is fixed to rectangle 32x32 even the object contain blank area ? Can I change the tilemap collision area ?

3. Tiledbackground collision area is fixed ? how to use tiledbackground for tilt area ?

Well.. I dont know how but maybe something related to this tutorial : scirra.com/tutorials/318/how-to-use-loader-layouts-to-make-custom-loading-screens

I just hope a nice guy could post an example events in editor start page. So I can learn how to do it right.

maybe you can try this event from game demos 'Kiwi Story' :

editor.construct.net

'name of variable' is the name of a local variable I used but is now deleted since I don't need it anymore.

Maybe because of that "local variable" ? since deleted maybe it cannot be recognize in the group ?

and maybe your "certain condition" still contain that local variable ?

what if make a temporary global varible with exactly same name like the deleted local varible, and after that try to drag the certain condition in to group again.

Just to figure out is it cause by the local variable missing or something else..

Hi Net :) thanks

I figure out something but kind of weird.. :D

Like you say new touch gets new id +1 each time.

since I do this stuff on laptop and my laptop screen is not touch screen, when I try the intermediate template like Touch Zooming, the ID only blink between 0 and -1

But when I try to export it to .APK and run it on phone (with touchscreen), I saw touchID keep increasing in every touch.

and yes.. i am thinking to make the grey box (sprite) separately become 2 different sprite object

then use "on touch object [ ]" to indentified the touchID and save it in certain variable
