NAME

SYNOPSIS

DESCRIPTION

The default properties that are relative to another object in this way are opacity, position, orientation and lifetime, though this set can be changed with the use of image_mask_set , image_mask_clear , image_mask_clearall , image_mask_toggle

The vid argument refers to the object that shall be reassigned, and the newparent arguments specified the object that it should be made relative to.

If the panchor argument is specified, it defines the positional anchoring space based on one of the following values:

ANCHOR_UL : upper-left, ANCHOR_CR : upper-center, ANCHOR_UR : upper-right, ANCHOR_CL : center-left, ANCHOR_C : center, ANCHOR_CR : center-right, ANCHOR_LL : lower-left, ANCHOR_LC : lower-center, ANCHOR_LR : lower-right.

If the anchor_opt argument is specified, further anchor behavior can be controlled. The valid values for anchor_opt now are: ANCHOR_SCALE_NONE (default), ANCHOR_SCALE_W , ANCHOR_SCALE_H , ANCHOR_SCALE_WH - the object size is now defined relative to that of the width and/or height of the parent. The relative delta is calculated based on the current scale versus the initial (storage without a texture backing) or the current storage size.

NOTES

1

Changing link ownership resets all scheduled transformations except for blending.

2

Rotation transforms do not take the positional anchor point into account, only its mask.

3

Link to self is equivalent to linking back to WORLDID .

4

linked scale means that 1px will be subtracted from id in each desired dimension when calculating final size as no object can go below 1x1 px size, making it otherwise impossible to describe the case where parent and child should have identical size for the shared dimension. hare dimensions

EXAMPLE

function link_image0()
      a = fill_surface(64, 64, 255, 0, 0);
      b = fill_surface(32, 32, 0, 255, 0);
      link_image(b, a);
      show_image(b);
      blend_image(a, 1.0, 50);
      move_image(a, VRESW, VRESH, 100);
      rotate_image(a, 100, 100);
      expire_image(a, 100);
