Attention

Information set with PUTSPRITE is initialized by the SCREEN instruction.

Reference

This instruction is easy for interchangeability with MSX BASIC. When the object is defined by other instructions, no same number it <スプライト番号> <オブジェクト番号>becomes it though it is possible to operate almost similarly as long as sprite is displayed by using only SETSPRITE and PUTSPRITE after the SCREEN instruction is executed.
<スプライト番号>It is possible to rewrite it freely by ordering the defined sprite OBJ because it corresponds by number of ..peel.. object and couple 1. Because the object defined by the SPRITE$ instruction is treated as TYPE7 (polygon of the orthographic projection from which the matrix is operated), the parent and child relation and the rotation, etc. can be similarly treated.
The registration order on the inside is almost the same as the object of TYPE7. <スプライト番号>When the object is not drinking TYPE7, it becomes the following.
1. Four tops are secured by using SETVERTEX.
2. Polygon ID that uses SETPOLYGON for this top ID is secured.
3. Scale XS, YS, and ZS of this object are assumed to be 0.99995(&HFFFC).
4. When the SETSPRITE instruction has not been executed yet, it <スプライト番号>sets it to the object that secures attribute ID by the SETATR instruction.
5. <スプライトパターン番号>Texture ID from which is referred for this attribute at the end ties.
The identification number secured here is the following number of ID used by each instruction at the end. It is the Overflow error etc. occur as long as only the SPRITE$ instruction is used though it doesn't get when each resource becomes insufficient.

<スケールX>, <スケールY>, <スケールZ>… All the values of the fixed zero point type are effective. The magnification when the top of the DATA initialization statement is read when giving it can be specified. 1.0 is given to all scales when omitting it.
<位置X>, <位置Y>, <位置Z>… All the values of the fixed zero point type are effective. When the top of the DATA initialization statement is read when giving it, the position is added. 0 is given to all the positions when omitting it. The position is added after the scale.
<カラー>… Fixed zero point type. The character color of 15 bit RGB color set to the attribute is specified. RGB(15,15,15) is given when omitting it. <カラー>Only when it peels off and , attribute data is secured newly, it is effective. When an existing attribute is used, it is disregarded.
<アトリビュートID>… When the registered attribute data is used for the polygon font, it has already specified it. The number of <アトリビュートID>data ..the allocation.. <フォント番号>should be more than the number of respects of ..drinking.. polygon. The Attribute size error happens when the number of data is insufficient. <アトリビュートID>When is omitted, it is newly secured, and the top data of the size in which is <フォント番号>used is allocated to the attribute data as an unused attribute identification number (the following number of attribute ID defined at the end). Attribute data over happens if the top data ..Attribute ID over.. any further cannot be secured if ID is not allocated any further.

Operation is detailed.

The character data of the polygon is defined in OBJECT by using the top data of BASIC internal organs. Besides this, top ID and polygon ID are automatically secured in the SETPFONT instruction according to the amount of use of the font data.
Top ID
In SETPFONT, the top data of the size in which is <フォント番号>used is allocated as an unused top identification number (the following number in top ID defined at the end). Vertex ID over happens if ID is not allocated any further, and Vertex data over happens if data cannot be secured any further. Top ID can be read by the VERTEXID(-1) function immediately before executing SETPFONT.
Polygon ID
In SETPFONT, the polygon side data of the size in which is <フォント番号>used is allocated as an unused polygon identification number (the following number of polygon ID defined at the end). Polygon ID over happens if ID is not allocated any further, and Polygon data over happens if the polygon side data cannot be secured any further. In secured polygon ID, top ID secured by this instruction immediately before cracks, it is hit, and a normal vector is made automatically. Polygon ID can be called by the POLYGONID(-1) function immediately before executing SETPFONT.

Example

"B" of the internal organs font is secured for top ID 0 polygon ID 0 attribute ID 0, it allocates to OBJECT 1, and it displays it.
OBJ CLEAR
SETPFONT 1, ASC( "B" )

Direct SETPOLYGON effective order  Indirect effect instruction

Function

The polygon side group (list on the polygon side) is defined.

Format

(2) SETPOLYGON{[(<法線ベクトル>]|[+]|[-]},(<頂点リスト>)
(3) SETPOLYGON<ポリゴンID>,<ポリゴンの数>,<頂点ID>,READ …DATA[(<法線ベクトル>],(<頂点リスト>)[,[(<法線ベクトル>)],(<頂点リスト>) …]

Example

(1) SETPOLYGON 0, 1, 0,,( 0, 1, 2, 3 )
(2) SETPOLYGON ( 1, 0, 0 ),( 0, 1, 2, 3 )
(3) SETPOLYGON 1, 16, READ

Parameter

SETPOLYGON should define the top data that registers and is bright and because the table is registered in the source, top ID be defined in independence with SETVERTEX.
<ポリゴンID>… Group number 0~ of defined polygon
<ポリゴンの数>… Number of polygons defined in this group.
<頂点ID>… ID of the top group that uses it to compose polygon. It is necessary already to have been defined. Undefined vertex happens in case of undefined. The number of tops is the same as the number of polygon sides or can be changed to another top ID if large. However, the vector of the law fountain is not calculated again.
<法線ベクトル>(x,y,z) The direction in respect is specified by the unit vector in the form of. <法線ベクトル>When is omitted, a suitable Catasen vector is made based on the top list. The method is the one (the search for three tops of different clockwise coordinates, and making from this outside product in three tops from among four tops). <法線ベクトル>The normal made from three tops can be made the opposite direction by giving minus (-) when is omitted. When nothing is given plus (+), it doesn't reverse.
<頂点リスト>It specifies in the form of (P1,P2,P3,P4). P1, P2, P3, and P4 are <頂点ID>specified to come to see the table of the polygon drinking in the top number in the top group clockwise. When the polygon is three corner type, the same number as p3 is copied when p4 is omitted. <頂点リスト>It <頂点の数>should be in the range of 0~ (-1) defined by the SETVERTEX instruction because it is the one that the <頂点ID>number was arranged. Vertex number happens when specified beyond the pale ..this...

Operation is detailed.

In the form of format (1), the polygon group is newly made. <ポリゴンID>The smallest group number that can be defined to omit is allocated. This number can be read by the POLYGONID(-1) function. <ポリゴンID>PolygonIDover happens if it cannot register more than.
It writes it from the continuation of the data of polygon ID defined to specify it in the form of format (2) at the end.
The form of format (3) defines the polygon data defined in the DATA initialization statement instead of the character string. As for data, it is necessary to define only an amount necessary to define it by the DATA initialization statement. It becomes Out of DATA error if data is not worth. It is necessary to define a normal vector and the pair of the list of the top in the same DATA initialization statement.
<ポリゴンID>Peeling off and defining it from the 0th , sequentially are the principles. For instance, when ID 2 is defined after ID 0 is defined, ID 1 cannot be defined back. <ポリゴンID>It misses and if it is <ポリゴン数>Onage, it is possible to redefine it later. Polygon size mismatch happens when differing from former number of polygons. It is the <頂点ID>same or should be larger in specified <頂点ID>, end at this with the number of tops. be definedVertex size mismatch happens when it is fewer than the number of tops at the previous state of K. The content of the polygon data is initialized by the SCREEN instruction.
  

Example

(1) SETPOLYGON 0, 10, 0
(2) SETPOLYGON -, ( 0, 1, 2, 3 )
(3) SETPOLYGON 1, 6, 0, READ

It is declared that (1) will define ten polygons by using the top in top ID 0 for polygon ID 0 in the future. Or, the declaration to define the polygon newly by using the top in top ID 0 for polygon ID 0 defined before again is done.
(2) allocates the top of two number top of one number top of 0 top number tops number 3 in top ID 0 in the first polygon of polygon ID 0 declared to be assumption as execution just behind (1) in (1) (polygon number 0). Because a normal vector is omitted, and the minus is given to the sign, a normal vector is defined so that the opponent may do a plane normal that connects the first three different points of two number top of one number top of 0 top number tops number 3.
0→1
↑↓ A normal vector is made on the screen and the other side.
3←2
Because as many as ten polygons ID 0 were reserved by (1), it is necessary to define it nine another times.
It is declared that (3) will define six polygons by using the top in top ID 0 for polygon ID 1 in the future. Or, the declaration to define the polygon newly by using the top in top ID 0 for polygon ID 1 defined before again is done. The defined data is read from DATA initialization statements as much as the READ instructions.
Example in DATA initialization statement of (3)
100 DATA ( 0, 0, -1 ),( 0, 1, 2, 3 )
110 DATA ( 1, 0, 0 ),( 1, 4, 7, 2 )
