・0, if not specified.

ANIMDEFSaveFlag

If 1 is specified, the content defined by ANIMDEF is saved without being cleared.

・0, if not specified.

XSCREEN Width,Height[,SampleMagnification[,CompositeMode[,AspectRatio]]]

Set the display resolution

・The size of the console (text screen 4) is changed according to the width and height.
・Other text screen settings remain the same.
・Graphic page sprite settings are changed according to the width and height.

Arguments

Width,Height

Specify the display width and height in pixels

Width: 128 to 1280

Height: 128 to 720

・A number that can be divided by 4 can be specified for both width and height.

SampleMagnification

Pixels can be subdivided to express rotation and enlargement more smoothly.

・It can be specified 1 or more, the product of width multiplied by sample magnification should be up to 1280, and the product of height multiplied by sample magnification should be up to 720.
・1, if not specified.

Composition mode

Specify the drawing method when the BASIC display is finally combined with the indicating display

0 Bilinear
1 Smart Nearest Neighbor
2 Nearest Neighbor

・0 is smooth pixel corner, but the whole image is blurred.
・2 is a clear display as a whole, but the pixel corners are jagged.
・1 is between 0 and 2.
・0, if not specified.

AspectRatio

Display aspect ratio: 0.1 to 10

・Square at 1, vertical when smaller than 1, horizontal when larger than 1.
・If not specified, width / height is set.

XSCREEN OUT Width,Height [,SampleMagnification[,CompositeMode[,AspectRatio]]]

Get display resolution

Return Value

Width,Height

The width and height of the display (in pixels)

SampleMagnification

CompositeMode

AspectRatio

ANIMDEF DefinitionNumber,AnimationTarget,DataArray [,Loop]

Animation definition

・The defined animation can be used with SPANIM and TANIM commands.

Arguments

3 "S" Magnification XY
4 "C" Display Color
5 "V" Variable (value of sprite variable 7)
6 "UV" UV Coordinates (definition source image coordinates)
7 "I" Definition Number

・If you add "+" to the end of the string or add 8 to the value, it will be the relative value from the animation start point.
・If you add "." to the end of the string or add 16 to the value, the sprite will be deleted when the animation ends.

DataArray

1D numeric array that stores animation data

Loop

Loop count: 1 or more

・Specify 0 to make an infinite loop.
・1, if not specified.

DataArray

・Animation data is prepared in the following order in the numerical array (up to 32).
・Time1,Item1,[Item2,] Time2,Item1,[Item2,]...

Example

DIM PANIM[ 6 ]
PANIM[0]=-60 'frame(-60=smooth)
PANIM[1]=200 'offset X,Y
PANIM[2]=100
PANIM[3]=-30 'frame
PANIM[4]=50 'offset
PANIM[5]=20
ANIMDEF 0,"XY",PANIM

ANIMDEF DefinitionNumber,AnimationTarget,@Label[,Loop]
ANIMDEF DefinitionNumber,AnimationTarget,LabelString[,Loop]

Animation definition (specified with DATA command)

・The defined animation can be used with SPANIM and TANIM commands.

Arguments
