RenderWorld [tween#]
Parameters:
| tween# - defaults to 1. |
Description:
| Renders all entities in the world. The optional tween parameter can be used to render entities at a point somewhere between their captured position and their current position. A tween value of 0 will render entities at their captured position, a tween value of 1 will render entities at their current position. Other values may be used for interpolation. Defaults to 1. Tweening is a technique used to allow games to have their game logic updated a fixed amount of times, e.g. 30, while having Blitz3D interpolate between these game logic updates to render as many frames per second as it can, e.g. 60+, with each frame different to the last. This results in a game which only has to have its game logic updated at half the rate of the renders per second, freeing up CPU time, while at the same time having the game run as smooth as possible on anybody's machine. Render tweening is quite an advanced technique, and it is not necessary to use it, so don't worry if you don't quite understand it. See the castle demo included in the mak (nickname of Mark Sibly, author of Blitz3D) directory of the Blitz3D samples section for a demonstration of render tweening. |
