Hello Guys,
This is a new one to ask for help.
Im trying to move an object from the bottom left corner to the centre of the screen - I understand that Get3DVector<>fromscreen commands will convert 2D X,Y
so if I set X=-50 and Y=screenheight-50 - this in theory would like the object to be not displayed until i change the X to increase and Y to decrease.
I may be doing something silly
Here is an example code with X and Y set to be off screen to start with
// Project: CarVUPHeli
// Created: 2019-03-15
// show all errors
SetErrorMode(2)
#constant screenwidth=1024
#constant screenheight=768
#constant fullscreen=0
#constant screenrate=0
// set window properties
SetWindowTitle( "CarVUPHeli" )
SetWindowSize( screenwidth, screenheight, fullscreen )
SetWindowAllowResize( 1 ) // allow the user to resize the window
// set display properties
SetVirtualResolution( screenwidth, screenheight ) // doesn't have to match the window
SetOrientationAllowed( 1, 1, 1, 1 ) // allow both portrait and landscape on mobile devices
SetSyncRate( screenrate, 0 ) // 30fps instead of 60 to save battery
SetScissor( 0,0,0,0 ) // use the maximum available screen space, no black borders
UseNewDefaultFonts( 1 ) // since version 2.0.22 we can use nicer default fonts
