Appendix 7. The runtime options

If you display the properties of an application (by clicking on the application in the workspace

toolbar), you will notice a “Runtime options” tab. This page contains important properties

to ﬁne tune the runtime.

• Frame rate. Set the number of frames

per second of the runtime. The default

value is 50, it can go from 1 (one step of

animation per second) to 1000 (twenty

times as fast as the default settings).

• Machine independent speed. This

option is specially designed for heavy

graphics games, with big objects that

take some time to be drawn. If you

notice a slow down in the animation

(meaning the runtime cannot run at 50

frames per seconds), it might be worth

to try this option.

• Run when minimised. If unchecked,

the runtime will go in pause mode when

the window is minimised. Check this

box to make it continue to run.

• Run while resizing. As a default, the

runtime is in pause while you are resizing the window. Check this box to make it continue

to run.

• Do not stop screen saver when input event. You might want to create interactive screen

savers, like small games. Use this option and the screen saver will not vanish when the user

presses the keyboard.

• Sound / Multi samples. Allows more than one sample to be played at the same time.

• Sound / Play sound over frame. If checked, the sounds (samples and music) will continue

from one frame to another.

• Sound / Do not stop samples when application looses focus. The default attitude is to

cut the sound when you activate another application.

• Display / Display mode. This option allows you to choose the method of displaying the

images used by the runtime. Standard uses normal display routines and work on every

machine. DirectX uses Microsoft DirectX interface. It is usually slower than Standard but

you might need it if your application uses the Change Resolution Mode option and has a

non-standard resolution (e.g. 320x200 is not available on all the machines with the Standard

display mode). DirectX + VRAM is usually faster, especially for scrolling applications,

but it can be also very slow with some ink effects or transitions, so it depends on your

application.
