Summary

Learn how to put your game into 1st, 2nd or 3rd person view.

Full Description

The system uses limbs to turn your game into the view you wish. Press 1, 2 or 3 for the different views while playing. Change the object number from 1 to the player object and tadaa you have views. Take out the two views you don't need and just use the view you do need. Goodluck.

`CREATE OBJECTS

MAKE OBJECT CUBE 1,20`Make our character

MAKE OBJECT CUBE 2,30`Make another object so we can see that we're moving

POSITION OBJECT 2,0,0,40`Position the second object away from the user

`CREATE LIMBS

` - 3rd Person View Limb

MAKE OBJECT CUBE 5000,.1`Create a "dummy" object

MAKE MESH FROM OBJECT 5000,1`Create a mesh or "blue print" of the dummy object

DELETE OBJECT 5000`Delete the dummy object to reduce lag, it's not needed any more

ADD LIMB 1,1,5000`Create a limb from the mesh "blue print" and then add it to object 1, our character

OFFSET LIMB 1,1,0,30,-70`Offset or Position the limb far behind our character (object 1) and slightly in the air

HIDE LIMB 1,1`Hide the limb so we can't see it, it's not supposed to be seen

` - 1st Person View Limb

MAKE OBJECT CUBE 6000,.1`Create a "dummy" object

MAKE MESH FROM OBJECT 6000,1`Create a mesh or "blue print" of the dummy object

DELETE OBJECT 6000`Delete the dummy object to reduce lag, it's not needed any more

ADD LIMB 1,2,6000`Create a limb from the mesh "blue print" and then add it to object 1, our character

OFFSET LIMB 1,2,0,5,0`Offset or Position the limb right where our character is, and a tiny bit upwards

HIDE LIMB 1,2`Hide the limb so we can't see it, it's not supposed to be seen

` - 1st Person View TARGET Limb

MAKE OBJECT CUBE 7000,.1`Create a "dummy" object

MAKE MESH FROM OBJECT 7000,1`Create a mesh or "blue print" of the dummy object

DELETE OBJECT 7000`Delete the dummy object to reduce lag, it's not needed any more

ADD LIMB 1,3,7000`Delete the dummy object to reduce lag, it's not needed any more

OFFSET LIMB 1,3,0,5,15`Offset or Position the limb infront if the character, so we have something to point our camera at, to make sure we're always looking forwards

HIDE LIMB 1,3`Hide the limb so we can't see it, it's not supposed to be seen

`LOOP OF EVENTS

DO` Do, this starts our Loop of what we want to be checked and completed over and over

`DEFINE/STORE LIMB INFORMATION

LIMBX1#=LIMB POSITION X(1,1)`Store the 3rd Person Limb's X coordinate

LIMBY1#=LIMB POSITION Y(1,1)`Store the 3rd Person Limb's Y coordinate

LIMBZ1#=LIMB POSITION Z(1,1)`Store the 3rd Person Limb's Z coordinate

LIMBY3#=LIMB POSITION Y(1,3)`Store the 1st Person TARGET Limb's Y coordinate

LIMBZ3#=LIMB POSITION Z(1,3)`Store the 1st Person TARGET Limb's Z coordinate

`1ST PERSON MODE

IF MODE#=1`If the Mode variable equals 1

POSITION CAMERA LIMBX2#,LIMBY2#,LIMBZ2#`Position the camera at the 1St Person Limb's coordinates

POINT CAMERA LIMBX3#,LIMBY3#,LIMBZ3#`Aim the camera at the TARGET Limb, so we are always looking forwards

ENDIF`End the if statement

`2ND PERSON MODE

IF MODE#=2`If the Mode variable equals 2

POSITION CAMERA LIMBX2#,LIMBY2#+OBJECT SIZE(1)*3,LIMBZ2#`Position the camera at the 1st Person limb coordinates (no bother in creating another limb, we can use the 1st person limb for this mode) but, when it comes to the y coordinate, multiply the object's size by 3 and set the y to this. This way no matter what the camera is always above the object.

POINT CAMERA OBJECT POSITION X(1),OBJECT POSITION Y(1),OBJECT POSITION Z(1)`Aim the camera at the character object, so we can still see it. Try taking this out and seeing what happens.

ENDIF`End the if statement

`3RD PERSON MODE

IF MODE#=3`If the Mode variable equals 3

POSITION CAMERA LIMBX1#,LIMBY1#,LIMBZ1#`Position the camera at the 3rd Person Limb coordinates

POINT CAMERA OBJECT POSITION X(1),OBJECT POSITION Y(1),OBJECT POSITION Z(1)`Point the camera at the character object so we can always see it

ENDIF`End the if statement

`CONTROLS: Moving forward and backward

IF UPKEY()=1 THEN MOVE OBJECT 1,3`If the upkey is pressed, move the character forward at 3 units per press

IF DOWNKEY()=1 THEN MOVE OBJECT 1,-3`If the upkey is pressed, move the character backward at 3 units per press

`CONTROLS: Turning left and right

ANGLEY# = OBJECT ANGLE Y(1)`Store object 1's Y angle, we need it for the next part of code

IF LEFTKEY()=1 THEN YROTATE OBJECT 1,WRAPVALUE(ANGLEY#-3)`If the left key is pressed then rotate object 1 on it's y axis, use the wrap value command to reset the value if it's over 360 or below 0, and rotate the object at a rate of it's Y Angle + 3 Units per press

IF RIGHTKEY()=1 THEN YROTATE OBJECT 1,WRAPVALUE(ANGLEY#+3)`If the right key is pressed then rotate object 1 on it's y axis, use the wrap value command to reset the value if it's over 360 or below 0, and rotate the object at a rate of it's Y Angle - 3 Units per press

`CONTROLS: Mode Switching

IF KEYSTATE(2)=1 THEN MODE#=1`If 1 is pressed, set the Mode variable to 1

IF KEYSTATE(3)=1 THEN MODE#=2`If 2 is pressed, set the Mode variable to 2

IF KEYSTATE(4)=1 THEN MODE#=3`If 3 is pressed, set the Mode variable to 3
